I don't think so. Anyway, when you are recording the Sun, there's a 10 minutes time limit at the top right corner, so you cannot record more than 10 minutes. But I guess this is for the file size limit. A 10 mins long RAW video of the Sun is around 15-18 GB.
A previously ordered a K&F Concept ND100000 solar filter arrived to me yesterday. I made a 3D printed filter holder to it. Works perfectly. It seems the image quality is better than with the original Seestar Sun filter.
