1 year ago PS. The interface speed tested with iperf3 computer to ds423+ is fluctuating between 1gbps and ~2.5gbps. The Sabrent adapter itslf tops out at about 3.5gbps when tested on a computer against the DS1821+ 10Gbe NIC (as expected with this chip and USB interface)
PS2. I've restarted my switch (managed), and retested with jumbo frames enabled manually - it works.

Description of the problem
There is no option to set the jumbo frames in the network interface. Dropdown shows only up to the default 1500. The interface is reporting correctly 5gbe, the netgear switch is recognizing the 5gbe connection and is by default jumbo frame enabled. Initially I've installed the 1.3.3.0-11 and then realized after reddit chat that I was on a pre-release. After uninstalling I've installed the 1.3.3.0-10, no change - same issue. I've upgraded again to -11, no difference. Lan Cable on the rear of the Synology was tested while plugged in and taken out, no difference.
