Can I change the link associated with my header button in my navigation just on a certain page?

This is a preemptive question. I am in the process of creating a website for a client. She has two different booking calendars. I am wondering if there is a code I can use to change the link attached to the button in the navigation only on specific pages. To give more context. The client is a virtual assistant but also provides mentorship. The main call to action will be a button to book a call for her VA services, but on the mentorship pages I want the navigation button to link to her booking calendar for her mentoring services. Is that something I will be able to do? Just want to know if it is even possible before I get too far into building the site and have to rearrange things if it isn't possible. Thanks in advance for any guidance!

@AlyssaIvonne Yes, it's achievable with custom scripting. To do this, you would require a business plan that allows you to integrate custom scripts.

Hi again! I am ready to start building my client's site. Is there a code I can use to change the link attached to the header call to action button only on certain pages? For example for every main page I need the button to link to one booking calendar, and on all my mentoring pages I need the button to link to a different booking calendar. Any help with doing this would be super appreciated!
