Yes, they'll allow you to make improvements to the genome (within what's naturally human) but I can't image they'd see selecting a sex, or a sexuality, as a genetic improvement.
Beowulf has always approved of changes to adapt people to harsh environments - the Meyerdahl mods for example. What they are vehemently opposed to is the "improvement" of the race - leading to a homo superior. The mods that Honor has, for example, fit her for life in a heavier that normal gravity field, but don't have the connotation that she is a superior human (although she is, as a result of her parents, but those traits were not selected for), and in fact, I suspect that the Mesa approach of "improving" the genome is going to back fire on them, simply because they will have eliminated some aspect of humanness that they considered irrelevant, that turns out to be critical in some situation - what situation I have no idea, but it is one of the risks of eliminating diversity.
