Is there an API command for NVR to change fan speed? I have a NVR5216-16P-I which has one fan that can change speed.

I would like to know if there is API to change fan setting to 'Self-adaption' or 'Full-speed'.
My thought it to use Home Assistant to set the fan to full-speed during the day and to self adaptive at night.
Is this API in the newest document @EMPIRETECANDY ?
