OEM partition on custom built PC

[PROGamer_199]

Hi, I've tried to use AMD StoreMi today but I got an error that says "Boot device split between two drives, tiering with this formation is not supported, please reinstall or migrate Windows so it only resides on one drive.". I've looked online and most people say that it's a partitioning issue, and after looking in Disk Management, I found out that my SSD has a 538mb partition reserved for "OEM partition". My PC is custom built by myself, no parts have came in a bundle, no parts have been reused from an older build. Everything was brand new. Is there a way to get rid of the OEM partition and make it one large partition with my SSD so I can use StoreMi, or is it necessary for my PC to function properly to have that partition?

Will it harm my OS in any way or is it "safe"? Also, thanks for the fast reply.
