Which direct mount hanger?

[MrFixit]

I have replaced my 10 speed Shimano cues mech, Cassette, etc., that was on my recently built Shimano ep800 powered CEF52, with a 12 speed Deore RD-M6260 Di2 mech, cassette etc., in the process I have realised how little I know about UHD’s and direct mount derailleurs! The frame was supplied with a UHD and I have temporary fitted a ‘hanger’ similar to a goat link, but it cannot be aligned to a position to allow me adjust the B screw correctly. The bike is rideable but far from ideal. Could someone advise me as to what Direct Mount Hanger I should get and where from?
I have seen some hangers on eBay UK being offered by Chinese sellers but I’m unsure if they would be suitable and, they could take between 4-6 weeks to be delivered to the UK. Thanks

on a UDH with 12 speed, the shimano stuff should mount to the hanger without a goat link?

I tried that, but the mech was hitting the cassette, when changing to the larger rings

if it's hitting, you need to wind the B-tension in.
