AMD GPU not being used by Debian Buster with kernel 5.10

I'm running Debian 10 with kernel 5.10 via buster backports on baremetal. The installed driver for amd is amdgpu and the output of dmesg from my understanding tells me the driver is being recognized,

and lshw -c video shows both the integrated and dedicated GPU

However when I run glxinfo -B or DRI_PRIME=1 glxinfo -B the output is

I have tried running programs that could use the GPU as well but they seem to keep using the VMWare llvmpipe gpu, the output of radeontop always shows up as 0%. How do I get my machine to use amdgpu?latest?d=yIl2AUoC8zA latest?i=yQVSbLRH_7Q:g5em_TeGfqs:F7zBnMy latest?i=yQVSbLRH_7Q:g5em_TeGfqs:V_sGLiP latest?d=qj6IDK7rITs latest?i=yQVSbLRH_7Q:g5em_TeGfqs:gIN9vFwyQVSbLRH_7Q
