No.

Micronovae are a recent theory for explaining observational data, having been suggested only a few years ago. So it will be difficult to make specific predictions about whether they will occur for a specific star system.

That being said, they would occur in a binary star system (2 stars in a gravitationally bound orbit) when a white dwarf accretes matter from the other star in the pair. Our sun is not in a binary system and isn’t a white dwarf, so a micronova can’t happen.

I haven’t watched the videos you linked but I would caution against listening to someone making that sort of claim. They aren’t operating in evidence based science.
