I can boot to the Open core menu without USB and from a partition ?

A few weeks ago I managed to install Mac OS Ventura on an HP laptop 440 g7The operating system works excellent with all its functions. But I am dissatisfied with the way to boot. That is, I necessarily have to use a pendrive available for when I need to get into hackingtosh. And it seems very impractical to always have to have the pendrive connected. Is there any kind of way I can boot hackingtosh without needing a pendrive?Thank
