glued

Hello, I purchased two bidets for my toilets at home. Was able to install one without issue, but am running into a glued hose attached to the water valve coming from the wall. I have a metal braided cable I want to replace it with. What is the correct way to remove a glued hose? Do I need to...

My preasure reducer appears to be glued in and not screwed in for easy replacement (like I have seen in several videos). Any advice on removing and replacing this?
