Hey y'all. I have a work pc that has chrome and edge installed on it, but can't have any extensions added due to security reasons. I primarily work with a web program that is purpose built for my job. I would to adjust the css of the website on a permanent basis in order to make my work easier. Is this possible using only the default browser settings / addons?

The f12 development tool has shown me that it's possible to make the adjustments i want on the fly, but I would like to make those changes permanent to my web browser.

As far as I know chrome used to support user scripts but has made it impossible to do with a modern version. I found less results for edge.
