So, both of the patches above need to be applied to ath10k-ct 4.19 driver?

I can apply this one to the 4.19 ath10k-ct driver too, I just am not using 4.19 internally,
so...well, no local testing.

It should be pretty easy for someone to write a patch to extend 'fwcfg' feature in ath10k-ct
to support this, or just hack in a commit similar to what you did to the stock driver if needed.
I'll very likely accept a patch that enables tweaking this based on fwcfg API.
