Remove/hide button Send mail to MRP controller on MD04

Hello experts,

I would like to remove or hide the button "Send mail to MRP controller" on the MD04 transaction (see attachment). This button is not part of the Navigation profile customizing where we generally customize the Tcodes shortcuts on the MD04.

Do you know if it is possible to hide it or delete it? And if so, how? Please advise.

Best regards,
