Well... the process cannot be changed. Confirmation hearings have specific procedures/rules.
Isn't that right, Merrick Garland?
And boy, did the Judiciary Committee honor their process for Amy Coney Barrett!!
Confirmation hearing procedures and rules get changed whenever the majority wants to change them. Or, more to the point these days, whenever McConnell wants to change them.
