Can they, though? In the past, Star Trek's output has been the most optimal when they were focusing on movies or television, with the time period where they focused on both, the 90s, viewed as a detriment to both mediums. Even in more recent times, higher ups in other franchises like the MCU have blamed their recent problems on dividing their attention between movies and television at the same time and in Marvel's case they are beginning to shift back towards focusing on movies exclusively.
One difference though is Trek I think will always be seen more of a tv franchise than a movie franchise. Most of Trek's best stuff has come from the tv shows.
