nope. you are stuck with the u/f. wrap the stock with 550 cord or a piece of rubber tube (thin) and it wont be so bad.
Did you consider putting a tactical stock on it? You can get the kits at a lot of online shops like Cheaper Than Dirt.

The mako group was developing a cool looking adapter when I looked. Not sure if it was released or finished. Before that it was trunnion work and out of my league.
The receiver would need a lot of work, because of the holes left open on the sides of an underfolder.
I would follow aquaman's advice...

It could probably be done but it'd be a pretty extensive (and expensive) project.
I'm not an AK guru but you'd have to swap out the UF trunnion for a sidefolder trunnion, so I'm assuming you'd need to weld up the current rivet holes, then re-drill for your new trunnion. If there's an angle on the back end of your receiver, it might have to be altered slightly for trunnion/folder assembly fitment.
You'd have to drill holes up front for your latch. There would possibly be some fitment issues with the latch too but it should work in a good smith's hands.
You might have to relocate your serial number if it’s in an inconvenient place that now needs to be riveted. If so, you’d need to request a variance from ATF to move the SN.
A good deal of work and money.

This!
Out of all the AKs: a traditional stock is the best (form, fit, & function), underfolders are just another anchor point on the body, while folding stocks are a good comprimose..

Since everyone's just saying not to do it without telling you why, and without knowing if you have the skills/tooling to do it, I'll be fair and at least run the process down:
Remove the underfolding stock, drill out the trunnion rivets, weld up all the holes, slant cut the back of the receiver, cut all new holes for the sidefolding mechanism and trunnion, rivet in sidefolding trunnion.
Grind/drill all front trunnion rivets, remove front trunnion, weld additional material on bottom of front trunnion to drill for front stock latch pivot pin, press barrel pin and barrel out of front trunnion, re-rivet back into receiver, drill front latch pin hole, drill/mill front latch hole in side of receiver, install front latch, reinstall barrel, reinstall barrel pin.
Install stock, hope you didn't **** anything up and have to do it all over again.
If you're feeling froggy, go for it. Be sure and post pics.
(Mario at Piece of History Firearms can certainly accomplish this for you, and it will look ****ing factory as ****. Don't expect it to be cheap....but it WILL be done right, without even the remotest possibility of any corners being cut. Troy at InRange may also be able to help you out, and is unbelievably good as well. I don't know how long either will take or what their backlog is at the moment)

There is one other option:

Thanks for taking the time to explain the process

I wanna go fast
I'd look at this option before selling or cutting it up.

If you're not too keen on the cheek weld, try wrapping it with some paracord. The underfolder may not have the best ergos, but it sure is sexy
