Member Sign Up Splash Page

Again a newbie question so thanks in advance for any assistance.

Is it possible to change the wording on the pre-set Wix member sign up / already a member? Log in splash page.

The membership section is for a specific element of members and rather than having to deal with anyone and everyone trying to sign up I was hoping to have some specific words as a deterrent like “memberships only available to X”

Thanks again.
