I don't know about PGI 20.9, the last one I tested was 20.4: here F95(!) 
support was still broken/incomplete.

Try to build the following:

https://github.com/cp2k/dbcsr/blob/develop/cmake/compiler-tests/f95-reshape-order-allocatable.f90

.. or run CMake for DBCSR and it will tell you directly:

   git clone https://github.com/cp2k/dbcsr.git
   mkdir dbcsr.build
   cd dbcsr.build
   CC=pgcc CXX=pgc++ FC=pgfortran cmake -DUSE_MPI=OFF ../dbcsr

If that succeeds but compilation fails later on, I will test again and 
see whether I can come up with another test case.

GNU and Intel (check versions on [1]) should work fine on x86, you can 
also look at the dashboard [2] to check for system+compiler combinations.

No, PGI is not yet supported. If you have a contact at PGI/NVIDIA, 
please also report the issues directly with them.

Best regards,
