Good question, I have same issue, unfortunately I have no clue about that.
I don’t have the tuya app to see if the device have this feature and I don’t see information about this feature on others zigbee project.
And as it use tuya cluster, there is nothing in zigbee specification for it.
At least there is a screenshot from that application which is in video.
There is a possibility of setting the Select type of your lamp and then Set the minimum brightness of the dimmer with description Please set the minimu brightness of your lamp and try to dimm your lamp. If the lamp is flashing or turned off, increase the brightness until it works well
Seems like there could be some additional attribute.
