Released in Jan 2023, firmware 2.21 added the option to activate Hybrid FIR functionality with the Fast start program. If you have a non-hybrid system, you do not have to update to 2.21.
With Hybrid toggle enabled, you will notice each fast start program will come with a preset intensity for FIR. Like all other parameters of the fast start programs, you cannot change the intensity.
