Seeking Advice: Navigating Belief and Action in Difficult Situations

Assalamu alaikum wa rahmatullahi wa barakatuh, my dear brothers and sisters. I find myself in a tricky spot at home and could really use some Islamic advice. When a person is in a place where showing what they truly believe might cause big problems-like getting punished or starting a huge family fight-is it okay in Islam to keep those beliefs to themselves? And what about when you're pushed to do things on the outside that aren't in your heart? Say, for instance, someone is forced into an act that goes against Tawheed, but inside they completely reject it and their niyyah is pure. Does that make a difference in the ruling? I know the concept of ikrah (compulsion) exists, but I'm a bit confused about how it works exactly and what the boundaries are. Honestly, I'm not looking for loopholes-I just want to properly understand our deen's guidance when it comes to dealing with pressure, staying safe, and the importance of intention. May Allah reward you for any help you can offer. Jazakum Allahu khayran.
