Yes some extra camber will help reduce this wear on outside edge. If track only car keep adding negative camber until you get fairly even wear on track days. However, if you primarily drive on street you will find you wear the inside edges while driving on street with extra camber, so you don't want to over do it - street driving is not aggressive enough cornering to roll the outside edges under like you do on track. For dual use street/track car you probably want -1.5 to -2 front at maximum. Track only can go as much as -3.5 front with your tires, as much as -4.5 front with slicks. Rear camber will be somewhat less - typically 1/3 or so less than front - depending on several factors, particularly how wide the rear tires are relative to the front - wider tires generally require less negative camber.
Since for street/track use you have to be modest with the negative camber, dismounting and flipping tires on the wheels before the outside edges wear too much, to balance out the wear, is the next best alternative to killing the tires prematurely by wearing off the outside edges as in your picture. For example if you find tires tend to last 4 events, flip them inside out on the wheels after 2 events.
But it is also a balance with the level of your driving - the faster/harder you corner the more you need extra negative camber to keep as much of the tread as possible flat on the track while cornering, and the more evenly your tires will wear on track with that extra camber. With track only cars running lots of negative camber, if you don't corner hard enough to roll the tires to use the negative camber you have, you will not have the tread flat while cornering and will lose grip. For that reason it is best for most to increase the negative camber progressively as they progress from green to blue to white etc., unfortunately with the high cost of full alignments that is not inexpensive if you are progressing rapidly. But most drivers do a limited number of events per year so the progressive approach works well for them. For street/track cars this is not generally an issue as you are limiting the negative camber to avoid destroying the inside edges while street driving.
Again this is not advice but sharing what I have learned through experience.
