No, because Chase can't hide is eyes or his pheromones.
And his parents are both dominant, so all their children are too.^^
I actually think that at least his parents wouldn't have any problems with Chase being a beta. Ashley married a poor plumber, who he met and fell in love with in hightschool, when they were still "betas".
In this universe dominant alphas can't hide their trait, the moment they manifest they have those specific eyes and pheromones. The only ones that can hide as betas are dominant omegas.
Chase is 100% a dominant alpha.
Serioulsy, his father would have probably been happy if Chase was a beta, one less who could become like Dominic (the grandfather).XD
And it probably could have helped to hide that his partner is a dominant omega.

Y'all ever think that dominant alpha trait from Chase is just a hoax or story built by his rich family so the more clout the family has the famous and richer Miller family is
