automating solo function

No, not possible.

But you can automate Mute but you'd need to do this to ALL of the tracks you don't want to hear

Or - you could split all the other tracks either side of where you want them to be muted and use the mute clip function

Or - if you already have any volume automation going on, you can reduce the volume to -INF during the part you want the other tracks to be muted.

You could even do this on a buss by buss basis to speed things up
