There are two things that are liquid at room temperature, are better than water for thermal transfer, won’t explode and can theoretically be put in a computers liquid cooling system.
Mercury, and Hydrofluoric Acid.
 
Now the issues for each, Mercury is extremely heavy and you need an obscene pump and stainless steel hardware. And if you were to spill something like a liter of Mercury in your home you’d have the EPA knocking down your door and locking down the entire towns water supply.
 
Hydrofluoric acid is a controlled substance because it’s used to make antidepressants, it can also kill you extremely easily because it eats away at flesh as it mixes in with water. So while you could easily put it in either a glass/ceramic water cooling system with maybe copper or aluminum contact  plates, any spill would destroy your pc, the desk, create toxic vapor which would kill you, anything that got on you would kill you, and honestly it’s just not recommended.
 
Water is the best for low heat dissipation use cases like computers.
Antifreeze is primarily to keep the liquid from expanding or contracting too much, and in the name, keep it from freezing. Glycol that’s used in antifreeze is actually worse for thermal transfer than water.
Putting antifreeze won’t help your system unless you put your pc outside in the winter.
 

I feel like there might be some misunderstanding here.
After actually looking at the website, which mentions everything you need to know.
You buy the Vest at $400
The vest requires the IN&BOX Module to actually work, so it is shipped with the vest. Upon receiving and setting up the vest you are given 2 options
Buy the device for $399 making your purchase actually $800 Lease the device for $120/Year or $12/Month One exception is there Optional Adventure Mode, which uses AI for off-road Crash Detection.
 
The FAQ should also be looked over, as they actually also do not just immediately shutoff the device under a Lease Agreement for Missing a Payment

You do not have a custom loop, the H115i is an AiO. There are ways to either jerry rig another AiO onto your GPU or to use (if available) some mounting brackets for GPUs. There are also expendable AiOs that have the option to add different blocks and or more radiators but yours is a plain regular AiO, non-expandable, probably a generic Asetek model. You can't just try and cut your way in there to add some connections since the radiator is most likely aluminium and every half decent block is copper based. Mixing those metals means galvanic corrosion.
 
Going custom loop will mean expenses around US-$ 400 and more even with cheap components from Bykski or Barrow to get a full custom loop with GPU and CPU included. Even if you'd skip the CPU since you have an AiO - you'll only save the CPU block and the 2 additional fittings - unfortunately about the cheapest part of the loop. The GPU full cover blocks even from Bykski are 100+, a radiator 60-100 (depending on size and brand, but with 2 components you're looking at a 280 or 360 at least, the more the better), pump-reservoir combo ~80, CPU block 60-80, tubing another 20, fittings (at least 2 for each, potentially adaptor fittings) probably 40+, a canister of distilled water and some biocide another 10-20, thermal paste to get it all mounted another 10, add even the cheapest good fans at 10-14 each on top (Arctic P12/P14 series).
 
And all that just to get a custom loop on a midrange 5700xt you actually need to find a block first.
