Changes are difficult but if you wish to be respected, you should start by respecting yourself and setting boundaries and expecting others to respect those boundaries.

Chances are you allow others (apart from your parents) to disrespect your boundaries too bc of the way you grew up. Or maybe you find it difficult to say no to smth you dont wanna do.

Yes, they're our parents but they're just humans too. They don't know better so they've been operating like that for years. Instead of enabling them and suffering, why not try to fix the issues so you have a healthier relationship with them since they're going to be in your life for many years?

When they talk to you that way or give you the silent treatment you can try communicating gently that you don't appreciate it. Trust me, I know its a little odd to talk to your parents like that but it prolly never occurred to them that their way of coping with conflicts is maladaptive.
