Hash a Hash???
If you apply and argon2 hash to a Shake hashed content would it be more secure?? or hashing the hashed its not a good practice??

If you're using an adequately secure hashing method to begin with, it's just not necessary. It would be like putting two hasps with different brand padlocks on a toolbox, only a minor additional inconvenience for the person who has already stolen the box. And if it were to become known you were putting such extreme efforts into encryption, it might cause suspicion that you were trying to compensate for inadequately protecting access to the data to begin with.
You can be sure a more compute-intensive method will become commonplace long before the currently popular ones become inadequate.
