Customising the Request Access page for SharePoint Online

Is it possible to customise the "Access Requests.ASPX" page to give specific information to people wanting to gain access to a page on your site, and give them a better experience?

The sort of thing I want to add to this page is as follows:

"This staff is for staff in the University, if you are a student who is also working for the University, please access this page when you are logged into Microsoft 365 with your staff account"
