Two things come to mind. 1. From a "keep the garage door shut" viewpoint, some garage door openers have a lock switch. My Liftmaster/Chamberlain for example, can be locked using a button on the opener so the remotes do not work. What brand do you have? 2. from the "My alarm wakes me up" viewpoint (if you have Ring for security), there have been several discussions about using a contact sensor to indicate when the garage door is opened. I installed this myself 2 weeks ago, very easy. It can be set to either be or not be part of your actual monitored alarm. I personally do not have it as part of the home alarm since I'm more interested in when I drive off and wonder if I left the door open, but both are possible.
