Short answer: Yes, stop asking about specific mods. Should I include 'x' in my smashed patch? You cannot use smash to load more than 254 full modules.
Long answer: It is the same as Skyrim SE itself, it has a limit of 254 'full modules' this is anything that is not an esl or esl flagged, including any esm. Short answer: Yes, but the limit is actually 254 full modules for Skyrim SE, not 255 mods. You can take my answers or not, your choice.
Disclaimer: I am not mator, perhaps he will disagree with some of these I did not ask him.
