No. unfortunately it's not working.
We have applied following parameters which is allowing us to deselect any selected row by Ctrl+Click but we are still able to select rows without pressing the ctrl +click after selecting first row.
In simple words, multiple rows should not be selected using only click, should be selected only with ctrl+click (it was there in 3.3)
selectionModel: { type: 'row', toggle: false, mode:'multiple', fireSelectChange: true }
