A couple ways.

For syntax regions there is the "matchgroup" keyword to highlight start/end markers separately from the rest of the region. :help :syn-matchgroup

For either matches or regions, there are pattern offsets you can apply, e.g. "hs=s+2,he=e-1" which specify a number of characters to leave out of the highlight but leaving the matched region alone, as well as a few others that specify where a match can begin/end. :help :syn-pattern-offset
