for 3 D volumetric mri brain tumor image and file extension is nii. with my matlab code as following
classNames = ["background","tumor"];
pixelLabelID = [0 1];
pxds = pixelLabelDatastore(im ,classNames,pixelLabelID, ...
'FileExtensions','.nii','ReadFcn',volReader);
Error using pixelLabelDatastore>parseInputs (line 202)
'FileExtensions' is not a recognized parameter. For a list of valid name-value pair arguments,
see the documentation for this function.

You did not indicate your MATLAB release.
The FileExtensions option was not available in some earlier releases. My memory is saying that it was added in one of the 2019 releases.

You will need to add the complete list of file names instead of a directory name.
dinfo = dir( fullfile(im, '**, '*.nii'));
filenames = fullfile( {dinfo.folder}, {dinfo.name} ) ;
