If the noise comes in through the power supply line, you can do a noise filter by passing the DC line through an FT140-43 ferrite core. By forming 6 threads from the wire on the ferrite core. I have a 2.5 mm2 power cable.
This acts as a choke against external disturbances. I have seen a similar solution on several websites.
When I used the v2 software and had various malfunctions, I did it, but not because of the noise.
I looked for the cause of the malfunction and also paid attention to the grounding at one point.
It's worth a try to make the noise smaller.
The picture shows that it is connected via an XT60 connector, so it can be removed if it doesn't work.
