Spacial anchors on a pi 5?

[Jtk1500]

Would there be any effective way for me to have spacial mapping on a pi 5 8gb. Im making an ar/vr headset and when i have a virtual window open i dont want it to move with myself i want it to lock in place similar to what you find on quest 3 passthrough. though it doesnt need to be perfect because im sure that will be difficult to achieve on a raspberry pi
