How to disable NetBIOS at Windows-Clients with DHCP-Option 43?

we have to disable NetBIOS on all our Windows clients via DHCP option 43. With network devices of other vendors (Cisco, Juniper, Mikrotik, etc.) it worked by adding the hex-value "01 04 00 00 00 02" to option 43. In different formats, of course, with blanks, without, with leading 0x, etc..
We have a site where DHCP service is running on Aerohive APs. Setting option 43 as Hex with the shown value did not work, because the service did not accept the Hex value and config-update was not possible. Rollback... We have one other option configured to use Hex as well, which works.

My question now is: how can I set option 43 correctly to deactivate NetBIOS?
Did I miss something?

Kind Regards
