Fujifilm F-Log in Resolve without an IDT

Hi all,
i am new to the Forum and also new to ACES.
First of all want to say thank you, for all the work you guys do in the forum.

I recently started working with a Fuji XH2s in Flog2.
I do not really understand how to create DCTLs.
All I know, the provided LUT from fuji looks awful. So my workflow using resolve color management and a LUT (only due to the lag of an IDT), will not happen.

@shebbe What would be the correct workflow or node structure, project setup, using your DCTL for A: going to rec709 and/or going to rec2100 st2084? If yo still need some testing material let me know. I would be happy to provide some F-Log2 Material.

I tried as follows but it did not seem to work:
Project settings:
DaVinci YRGB
Timeline Colorspace: DWG/intermediate
Output Color Space: Rec709.A

Node structure:

Your DCTL → A node for grading → ODT using a CST from Aces AP0 and ACES CCT to Rec709 Gamma 2.4.

However, enabling and disabling the node with the DCTL has no effect at all.

Thanks for your kind help.
