Change/update canonical tag when global canonical tag is set

Hi,
I have enabled global canonical tag in the weblfow, but would like to change or update the canonical tag on a specific page. How to do it??

For example:- https://www.example.com/abc has canonical tag as set by the global canonical tag url is https://www.example.com/abc. But, I need to change it to something like https://www.example.com/xyz

P.S:- It’s not a CMS collection page, it’s a static page.
