Cisco IPV6 config
I have new c9300 switches (pair), When I program an interface, the interface auto adds:
ipv6 address dhcp
ipv6 address autoconfig
ipv6 enable
ipv6 dhcp client request vendor
I have tried the 'no' cmd to all these entries - no luck
I have also tried the global no ipv6 unicast-routing
Am I missing something?

Look at for the first instance of these two:
ipv6 address autoconfig
ipv6 enable
Are they occurring at global?

Have you tried no ipv6 enable under the interfaces?
**EDIT** Sorry didn't see Atlas already mention that.

One other thing
Go to the host connected to one of those ports and turn v6 off. See if that clears the interface config. May need to run the no ipv6 enable on the interface after.
