When editing my photos I saw that there were about 6 red dots. are these hot pixels? Sensor is clean and never photographed laser shows! What can I do?

Could well be. Nothing much that can be done apart from either a sensor swap or a re-map of the sensor.
Try changing the date in the camera a month forwards and restart the camera, it ought to do a darkframe shot and map out those hot pixels.

It is complicated, Google tells me.

On the A7s3 it is easy:

I do not have that option on my A7r4, so I guess I have to do this:

or this:

I want an firmware update....

changing date in camera, remapping, didn't help!

I'd try it a few times before giving up on it, make sure the camera goes through a funny sounding shutdown (the shutter will cycle and a few seconds later shut again).
