Shortcut "lock active layer" ?

Hello everyone is there a way to lock the current layer with a shortcut ?

I'm aware of the command ctrl + 2 but this is not what I'm looking for.

I'm basically in the process of speeding my workflow and working exclusively with a drawing tablet  and shortcuts.  and I have to say I'm pretty  surprised by the huge amount of basic functions that are not assignable to shortcuts…

so after some research I come here because I don't find any solution  and I guess my only way to go with this would be to run a script and then I sing this script activation to a target with a third-party program right ?

and then you had to learn how to code to  use illustrator
