How to override Build in Plugin?

Thank you. I got that what should I do.
My purpose is that override that plugin because I found a bug in virtual camera project from EpicGamelearning.
I know where is the bug.
Can I change the plugin without impact to created project from EpicGameLuncher learning?
Is that easy?
I want to know If I create copy plugin from Engine and when how much take to impact already created project.
In other words, Can we replace Engine plugin to the project plugin?
I guess that impossible. What do you think?
