Hi,
I don't think this is possible at the minute. The initial release of the DS8A10 (model 5341-A01) comes in its own rack, similar to the previous version the DS8910 model 994. I would expect a rackless version to follow at some point, and I was expecting this to be announced in the second half of 2025. I'll see if I can find some roadmap info and provide you with an update.
Thanks
Darren
