That was my initial assumption, considering that this SKU is refitted enterprise Instinct card.
Initially I installed required packages for PRO 20.40 drivers manually. Detailes are in this post: Can't enable OpenCL for AMD RX 5700 XT on Linux - #9 by silex
However, right now I installed non-PRO variant of 20.40 driver with ./amdgpu-install --no-dkms --opencl=legacy,pal --headless and it works.
Under Debian both 20.45 and 21.10 drivers don’t work with Radeon VII.
I’ll give Penoza’s idea a try, and report here.
