How to Practice Islam Quietly Without Changing My Culture

Assalamu Alaikum, everyone. I’m a revert from a non-Abrahamic background, and right now things are a bit tricky at home. I can’t openly share my faith because it might cause serious issues. To avoid worry, I told my parents I follow Christianity, just so they don’t get the wrong idea. But honestly, I want to just keep my Islam between me and Allah. I don’t feel the need to show it off or mix my religious life with my cultural one. Is there a way I can practice secretly while still fitting into my usual culture-like my regular clothes, eating halal, keeping my name, and looking the same? I don’t wear a thobe or have a beard (I’m not that old anyway). Any advice would be appreciated. JazakAllahu khair.
