Can you rematch the gym leaders and the Elite Four members multiple times in S/V?

Question

I managed to beat the entirety of scarlet and wanted to know if there was any way to rematch the gym leaders/ elite 4 members more than once since I enjoyed battling against them and think they’d be a good way of getting more money and exp.

What about the School Brawl Tournament? Isn't that a good enough method of farming EXP and Pokedollars?

Yea but it’s only the academy staff, your rival’s and geeta. What I’m asking is if you can rematch the gym leaders and elite 4 members more than once.

Answer 1

Each gym leader has beefed up a little bit, evolving their original party and adding in a few new creatures to make things a bit harder. You will not need to complete the gym test again. Just walk into the building and you’ll a chance to get battle the leader. You can only rematch each gym leader once (according to what we’ve experienced, at least).

The above quote answers your question. The answer is No.

Once you beat all the gym leaders for the second time, you’ll be summoned back to your school for the Academy Ace Tournament, which effectively replaces the series’ historical option rematch the Elite Four. Rather than spamming the Pokémon League, you’ll be able to fight four random students and teachers from school at high levels for money and EXP.

The second quote provides an alternative method of farming EXP and money.
