Perez's optimism about the race on his home turf is fueled by his solid performance at the Circuit of the Americas.
"At times I had very good pace," Perez noted.
"But we're still lacking that consistency. I think we know what we did wrong on the weekend, so we are really optimistic going into future races. Hopefully, we can improve that."
When asked if he is starting to get to grips with his RB19, the Mexican responded, "Yes, I am. I think we did very good steps.
"Unfortunately, we didn't get to show it because we took a bit of a wrong direction on the setup, given that it was a sprint race.
"But I'm still very optimistic for Mexico. We know what direction we need to take, so hopefully, we get to show that."
The FIA's decision to disqualify Hamilton after the US Grand Prix is a vital break of luck for Perez as he looks to secure P2 in the drivers' championship and help Red Bull deliver their first ever 1-2 in the constructors' championship.
Perez has now stretched his lead over Hamilton to 29 points.
