Using parallel netcdf for history writes (io_form_history=11)

I a having issues using io_form_history=11 in my wrf runs. It seems when I configure , I get this message:
NetCDF version: 4.9.0
Enabled NetCDF-4/HDF-5: yes
NetCDF built with PnetCDF: no

I do have parallel netcdf libraries in this module: parallel-netcdf/1.12.2-intel-20.0.4-prhlslt
Do I need to build NetCDF differently to use io_form_history=11?

The output of NetCDF built with PnetCDF: no refers to whether netCDF was built with pnetcdf (as viewed with nc-config --has-pnetcdf). This is different from parallel-netcdf io_form_* = 11 which refers to PnetCDF : GitHub - Parallel-NetCDF/PnetCDF: Source code repository of PnetCDF library and utilities

To enable PnetCDF / io_form_history = 11 you should build with the environment variable PNETCDF set, similar to setting the NETCDF environment variable.
