I guess not the UPS it-selfs, but I can see the USB device in the info center. If I try to enable the UPS in the Synology settings the message is: No UPS connected or similar. I think its just an issue of an unsupported device. So my idea is to use an external UPS server on Docker.
Update: After some reboots the UPS was recognized and is working as well 
It‘s magic…
Kindly, how did you manage to make the UPS recognized, is it listing on Hardware compatibility list: Network UPS Tools - Hardware compatibility list
I have APC BE650G2 Back-UPS and still not recognized.
