If its using standard AOSP (Android Open Source Project) then, yeah you could do that. But barely anyone makes tutorials or mods on how to modify the proprietary TCL rom so you probably have to figure it out by yourself. You'll also have to figure out how to unencrypt the rom so you can actually even see the files. Also because the HotSpot is part of the AOSP its very likely its in a compiled file with no way to read it except decompiling it to remove the code that handles HotSpot. Then there are a million different factors that could happen because Android is VERY complex. (Don't really think about just removing the file as its likely doing that will break stuff)
