Probably the simplest way is to adjust the output volume.
However, I don't think it can be said enough: presets are made by someone with a particular guitar (with its particular strings, pickups, body, etc.). If you have a Strat, but the preset was made by someone with a Les Paul, you're never going to hear the same thing that the preset maker did. Or if you and the preset maker both have a Strat, but you have high-output pickups and they had low-output pickups, again, the input levels they need and that you need are likely going to be quite different (and the output sound will, again, also be different).
So there is really not too much point in worrying about the output levels of the various presets. They could really only possibly be consistent if just one person, with one guitar, and one audio interface were making all the presets -- which is probably not practical (or even desirable).
The most practical thing to do is to just adjust any presets you're trying out and, if you want to, save your tweaked version in your own folder of "homebrew" presets. It's not like they take up a lot of disc space.
