Cannot set frame rate

I purchased Arducam 1MP*2 Stereoscopic Camera Bundle Kit for Raspberry Pi, Nvidia Jetson Nano/Xavier NX, Two OV9281 Global Shutter Monochrome Camera Modules and Camarray Stereo Camera HAT

I instaled the drivers for V4L2 OBISP Driver for the Latest RPi OS Updates (Kernel 5.4.79 and later) - Arducam
But cannot see any option to set frame rate.
Further, is there any way to save the video output at 50 fps or higher? all the tutorials talk about saving an image.
