You can buy little ESPHome devices that will speak it’s local serial protocol and control it. (And then link to them how you want)

It’s incredibly annoying and dumb and I now have to get some. grumble

You can just use a relay to open and close the door if that’s all you want.

Edit: no you can't, if it's the fancy one. You gotta hack a switch like this: LiftMaster 883LM Security+ 2.0 MyQ Door Control Push Button

Sort-of: the newer ones require the physical button to speak the same rolling code protocol the remotes do. So, yes: but you have to modify a real door opener. ratgdo has the advantage that it pretends to be said door opener.

There's often a pair of pins on the internal board that you can attach a relay to. Shorting the pins causes the door to close.
