@Axolotl_cpp in most binary distros you cannot disable most of mesa drivers, you do not need.
you can try something like

cat /proc/$(pgrep <process>)/maps|grep libdrm

for any gui process to ensure that all existing drivers are loaded. You will keep LLVM in any gui process even if your drivers does not need it (because others, that need it is linked to llvm)
Only source-based distros allows really disable it
