I understand that you wish to shuffle the fileDatastore. You can utilize the shuffle function to do so. You can use it as given below –
fs = fileDatastore(path, 'ReadFcn', @load)
shuffled_fs = shuffle(fs)
Link to its documentation –

I get same error on R2019b as does Haoqing LI (another poster just asked same Q? and this thread showed up in the automated links system so came to investigate).
Dunno' what is different w/ the release Ayush Laddha used, but
>> ds=fileDatastore('3*.xlsx','ReadFcn',@readtable)
ds =
FileDatastore with properties:
Files: {
'C:\Users\...\Documents\MATLAB\Work\3-15-17.xlsx';
'C:\Users\...\Documents\MATLAB\Work\3-16-17.xlsx';
'C:\Users\...\Documents\MATLAB\Work\3-17-17.xlsx'
}
UniformRead: 0
ReadMode: 'file'
BlockSize: Inf
PreviewFcn: @readtable
ReadFcn: @readtable
AlternateFileSystemRoots: {}
>> ds=shuffle(ds)
Undefined function 'shuffle' for input arguments of type 'matlab.io.datastore.FileDatastore'.
