Wearing a kippah in lue of observing shabbos

I am baal teshuva and am in the early stages of learning. I have Jewish ancestry but was not raised in the faith, nor were my parents so I am pretty far removed. Observing Shabbos isn’t an option for me right now due to life circumstances but I want to pay respect to the day in another way if possible. I was thinking that wearing a kippah on just that day might be a good way of doing that. Again I’m very new to learning. Any information on what to do if I can’t observe shabbos right now, or information on Kipahs would be very appreciated thank you
