See netcdf version of file

[ATYslh]

Hello everyone,
I'd like to know if there is any way to see in xarray which netcdf version/format a file is using.
I know that I can do something like this with the netcdf4 python library:

from netCDF4 import Dataset
x=Dataset("CLCH_ts.ncz","r")
x.data_model
>>>'NETCDF4_CLASSIC'

Is there a way to do this with xarray? I want to access files only once if possible, because retrieving the data can take a while, therefore I try to avoid opening the file with xarray and the netCDF4 library separately.
The most important distinction for me is "Is it netcdf4 or something else like netcdf2". I guess the engine should know what type it is, but I have no idea how to access this information.

There isn't a way to do this without using netCDF4 directly in some way
