Hmm....
1. Try to film stuff when they are not around or inform them not to enter the room when you are filming and hang a "DO NOT DISTURB" note on the room when you are filming(I tend to do that)
2. Try to film stuff at a friends house or find a nice quiet spot outside where you can film your vlogs
3. Try to do some challenge videos outside and etc. - That is a bit hard for me given I do my vlogs with a mask and in general I do not show my face, but you can be creative
4. Find your own apartment/ house to live in where nobody will disturb you
