You can absolutely get hybrids with a manual system, they’re just rare. The Honda CR-Z, for example, is a hybrid with a manual transmission. The motor is just attached to first gear and/or the engine flywheel. There’ve also been countless hybrids over the years that are hybrid attached to a DCT, which is a glorified manual transmission. Most non-eCVT full hybrids similarly bolt a conventional transmission after the engine/hybrid system, so it’s not implausible for one to exist with a manual. It’s just not worthwhile, most of the time, probably because it adds extra factors that need dealing with compared to an automatic/CVT.
eCVT hybrids, on the other hand, are a separate type of transmission, so building one to be manual would not be possible.
