I assume this is one of Tuya devices, so maybe you can try using the Tuya integration described here.
I have ordered similar Tuya Zigbee roller shutter modules but I got WiFi modules instead so I was also looking a way to connect them to OH and blocking their Internet access few days ago and I succeed.
Via MQTT it was possible to change the travel time which was 10s by default.
EDIT: I forgot the fact that to go this way you will need some Tuya zigbee hub, so my reply will not be of any help to you
