Rail (625Wh) -11 mm offset sound a bit to much for my trek Rail

[Emilio-Trek rail 9.7]

I am thinking of buying this chainring for my Trek Rail (2021 model) but a -11 mm offset sound to much!
I though boost was +3mm. so thsi wuld mean a -14 mm chain line?
If any one has used this offset on a trek rail or knows how to calculate if it will work on not?
It would be greatly appreciated

No...that chainring is probably for a fatbike
