Q: Nikon lenses on Fuji camera and changing aperture with ring

[Scam]

I've been gifted a Nikon D90, with a Nikon 18-105, Nikon 50mm f1.8 and Tokina 11-16 f2.8.

I already had been using my own Nikon 50mm on my Fuji XT10 with an adapter so was messing around with these 'new' lenses yesterday. But I realised they don't have aperture rings so not sure how I can change aperture? Can I not use them properly?

Not hugely fussed as they'll probably all be stuck on the bay apart from maybe the Tokina.

You can use an adapter ring for Nikon G lenses which has a pseudo aperture ring. I have a Fotodiox pro adapter that I use on my XE-3.

Is that the only way for them to be workable?

If so, rather than spending £50 of my own money maybe I'd rather just sell the Tokina for £250 odd
