Not that I'm aware off. As far as I can tell this is one of the limitations of the Elements version. In Photoshop you should be able to find the option under the 'Edit' menu (or by pressing control-alt-shift + k on Windows) but that doesn't work.
However... I did notice that the data folder of PSE 2021 ("%APPDATA%\Adobe\Photoshop Elements\19.0") has a 'Presets' subfolder which in its turn has a 'Keyboard Shortcuts' subfolder. So if that folder is actually used (I doubt it) then it might be theoretically possible to put a matching configuration file in there to set this up. Of course... good luck trying to find out the right formatting 😉
So summing up: I don't think this is possible with PSE.
