You want a quiet shutter, you want mirrorless. I don't have these Nikon models, but for Canon, if they have a silent (more like quiet) shutter option, it comes only at a reduced frames per second. Look at your manual and setting options and see if you can get quieter with a lower frame rate. Or, dump these DSLRosaurs and join the silent swans of mirrorless.
If you get the Nikon Z9 or Z8 you have totally silent shutter with no reduction of frames per second. You want shutter sound on these cameras? It would come from a little speaker.
