Compiling with both ath10k-firmware-qca9984-ct and ath10k-firmware-qca9984-ct-htt

I would like to try out the ath10k-firmware-qca9984-ct-htt firmware for my R7800. How does one switch between it and the ath10k-firmware-qca9984-ct firmware? Should I compile both as modules? The default has ath10k-firmware-qca9984-ct as a built-in. Thanks.

They're always build as module!

You can select one as built into the image and the other as package only
Afterwards you will find both ipk packages in bin/target/{target}/{subtarget}/packages.
