How to change the default port (443) for PHPMyAdmin Custom URL?

I would like to change the default port (443) that is used to access the PHPMyAdmin Custom URL. I work with nginx & php fpm 7.4 - I only want PHPMyAdmin to be accessible via a custom port and not the default port. Something like this: https://my-server-domain.com:35274/my-custom-pma/

How can I do this modification?

Run Nginx on a custom port
And then you need to make some custom changes have no idea what exactly

I already have the HestiaCP running on a custom port. But I also need PHPMyAdmin running on a custom port. Hope someone can help me out.
