iPmokeSot this is allowed if you do it the official way (link above) or if you use external software while in LAN mode (else you'll get banned) https://plutonium.pw/docs/anticheat/
I did some research for some days and I couldn't find anything that works for PC. It seems like there is a paid tool that works with a few scripts and also an injector that works with one particular menu for Plutonium but I didn't try it.
What I can tell you is to never inject while not in LAN mode or else you'll get banned
