I've never seen or heard of a nonreplaceable tip being re built. That doesn't mean it cant be done but I'm not sure you'd be able to pull the two sides back together to properly rivet.

I already have a replacement bar with a serviceable tip on order, this one will probably get scrapped.
You used to be able to replace the bearing and nose sprocket in those types of bars but i have not heard of it being done for a long time. You just grind the heads off the rivets and push them out to remove old sprocket and bearing. The new sprocket and bearing would be wrapped in paper to hold the rollers in. You just slid it in the tip of the bar then removed the paper and then put new rivets in and peened the ends of the rivets

The groove in that bar looks badly worn in parts. People will tell you the groove can be rolled and squeezed back into shape. I wouldn't advise doing that.
Rivets ? The sides are spot welded on every bar I've seen in the last few decades.
Buy a new bar, and get a new drive sprocket too.

Not worth the time and effort

If you are interested, and have the time, take yours apart, if only for the experience. If just jammed up with dirt, or something, you may get it back to useful condition.
If the parts are bent or damaged, that would be another story.
