electric tailgate strut replacement 2017 superb saloon

hello, has anyone on here replaced the electric struts on their tailgate ? if so, do they need skoda to code them? i know skoda say they need to code a lot of stuff but i also know sometimes they dont actually need to do this....also, can i put gas struts on instead to save heaps of cash if its going to be expensive?   (260,000 miles so dont really want to be spending tons on this fix,) thank you !
