Do i need a sag bracket?

i recently swapped from a 4060 to a 7900xt. i’m running an inverted build so my gpu is upside down and really high in the case so there aren’t any sag brackets i can find online. i’ve been using a piece of wood but i don’t really like it and would like to get rid of it if i can. if i remove it the gpu sort of rests on the ram slots and i’m not sure if that’s bad for the ram or if it’s good by releasing some pressure off the gpu.
