I am not sure if you wanted more info, on this, (since I do not know if this may be your snake's problem) but I'll go ahead and add the following:
If the cause, of your snake's nose injury, is due to nose rubbing... The solution would depend on what the enclosure is made of, or figuring out what else there is that the snake is rubbing its nose on, &/or figuring out the cause for the nose rubbing.
If it's an object... removal, of the offending object, is, of course, the route to take (if the snake, habitually, rubs on the object... not if it is only when shedding or if just after eating).
Usually, though, it is the enclosure (due to snake trying to get out) that creates injury due to the snake rubbing its nose on/along it.
If the enclosure is made of wire/mesh/screen ... the best solution is to get a different enclosure (one that is not made of wire/mesh).
Though glass is not near as bad as wire/mesh... If the enclosure is made of glass, placing something along three (or all four) sides (so the snake cannot see through) can eliminate, or greatly reduce, the amount of nose rubbing.
If it's due to a screen top.... getting a different top/lid, or using your imagination for a solution (rigging the screen top in such a way that it eliminates, or reduces, the amount of rubbing on the screen), would be something you could try.
Stress, in that the snake does not have enough room or enough hides, can cause nose rubbing. If the reason, for the nose rubbing, is due to this ... The solution would be to set up more (amount), or more adequate, hides ... &/or to get the snake a larger enclosure (along with more/adequate hides).
BTW Another reason, for injury (to nose or otherwise) could be due to a light source being too close to the enclosure (heating up a portion enough that it could cause a burn)... with, or without, the snake being a "nose rubber"... 'course, worse if the snake is a "nose rubber".
Solution would be to not place the light source directly on top of enclosure &/or to not have it so close (or without something in between the light source & enclosure) that it can create enough heat (upon the glass, metal, etc.) that could cause a burn.
