Lost camera focus options after migrating to Klipper

So I am a newbie with Klipper, just finish migrating my homemade printer from Marlin+Octoprint to Mainsail on Klipper.
The camera is a PI Camera, model OV5647.
This is my crowsnest.conf:
[cam 1]
mode: camera-streamer
enable_rtsp: true
rtsp_port: 8554
port: 8080
device: /base/soc/i2c0mux/i2c@1/ov5647@36

The image is showing no problem, but I am not able to adjust the focus, neither autofocus is giving me acceptable results.
I have already checked [printer address]:8080/option, and focus options are not even listed.
On Octoprint I used to be able to adjust the focus.
