Prevent GTM scripts to be loaded on certain pages / urls

Hi.

Is there a way to prevent GTM scripts from loading on certain pages/urls?(from a plugin option or PHP snippet)?

I have landing pages external to my site which are integrated from urls like https://mywebsite.com/landingpage.
On these pages I end up with duplicates of GTM scripts. I have the impression that they are integrated first time on the site where the landing pages are created, and a second time by GTM4WP when the page is accessed from the site URL.
I would like to be able to prevent GTM4WP from embedding the script on these pages.
