Are there any disadvantages in buying Outward at GOG.com instead of Steam? Do mods actually work properly in the GOG version?

I want to buy Outward, and I usually buy games from GOG and avoid supporting Steam if I can. However, I have read that there can be problems with launching Nexus mods with the GOG version.

Is it true? If so, can it be solved?

I don’t want to buy the Steam version, but I will have to if the GOG one turns out to be incomplete.
