here is the code: https://github.com/aryanchoudharypro/bootswap

@Aryan ok not gonna lie this is cool as heck. I've been wanting this, as external Linux drives I plug in show up as firmware entries in BCD it's just a matter of swapping, if this can go beyond BCD to the UEFI level, even better, just haven't seen a good way since I know WMIC is dead these days argh. But great on you if you found a solution!
