I would target the following which should result in a low rate of pH rise.

FC 4.0 minimum
pH 7.7
TA 80
CH 400
CYA 80
Salt 3000

If the pool is not in direct sunlight, then you could have a lower CYA of, say, 50 ppm, and either have the pH target be 7.6 or the CH be 300.

Usually in an SWG pool if you try and keep the pH lower at 7.5 then you fight a pH rise more than if you target a slightly higher pH. The reason is that a lower pH or a higher TA or increased aeration will result in faster rise in pH.
