That really applies on both sides. This is such a nothing issue - it defaults to what you'd expect for a cis character, so you can literally ignore it if you aren't going to play a character whose pronouns and body type do not align.
But, someone modding their game doesn't effect anyone else playing it, whether that's removing the pronoun selector in Starfield, adding a pronoun selector to Skyrim (even supporting multiple pronouns with different frequencies for each), turning every hold banner in Skyrim into a pride flag, removing pride flags from Spiderman, turning Skyrim dragons into Thomas the Tank Engine, or adding the ability to fuck Skyrim dragons. All of those are mods that exist, BTW.
And this only makes the claims that "this is not a political statement" more absurd. There may be room to argue that the original decision to let players select their pronouns is not political, but both the mod that removes it and the removal of that mod from Nexus are just pathetic attempts to get back at the other side. Can't get more political than that.
Of course this is political - because bigots made trans people's existence a target of their politics. Defending them against that hatred and abuse is not somehow equally wrong, compared to that hatred... and abuse.
