New Extruder - Cetus MK3

Any idea if it would be possible to install a new extruder like the E3D Hemera without having to switch off of UpStudio. The Cetus extruder just doesn’t work. I’m on my second extruder unit and have bought nearly 10 nozzles stock including the v2 upgrade but the filament always escapes the nozzle and ends up leaking onto the sides and ruining the print. I’m on a Cetus MK3 that is about a year old.
