PMP used double asterisks in its file paths to expand directories and files, for example, the infile: /global/cfs/projectdirs/m4931/gsharing/css03_data/CMIP6/CMIP/INM/INM-CM5-0/amip/r1i1p1f1/**/ta_*12.nc was used, then xr.open_mfdataset was used to open it. It seemed that xarray does not support it. The glob expansion is needed before the file was opened by xarray.
