Can you remove Pegasus from your phone?

Excuse me, but I was wondering if you could clarify something for me. I've heard about Pegasus, this alleged spyware that can be installed on smartphones. It's a bit concerning, to say the least. So, my question is, is it actually possible to remove Pegasus from a phone once it's been installed? I understand it's a complex issue, but I'm just curious if there are any known methods or steps one can take to protect themselves and their data from such a threat.
