Is there a way to do active track or follow me in s-mode?

No, the option is not available unless you are in P mode.

The obstacle avoidance isn't fast enough to work in S mode anyway so it wouldn't be safe.

can p mode speed be adjusted or slightly increased

Yes, by upgrading to the Pro or Advanced!
