Boot Logo Display using APRIORI DXE

Hello Everyone!

I am working on NVIDIA jetson agx xavier board have edk2-nvidia v35.6.3. I want to display logo as soon as Possible. I studied DXE a little bit and figured out that edk2-nvidia loads DXE mentioned in APRIORI DXE first and then other things. Thats why I started adding the logo and graphics dependencies in APRIORI DXE so that I can get the logo on screen as soon as Possible. But I am stuck into dependency errors. Can someone guide me what should be the exact DXE order in APRIORI to load display logo as soon as possible

Here is my Current APRIORI DXE values in jetson.fdf file

Start with the APRIORI DXE block in jetson.fdf and the dependency errors in the supplied boot log, especially the VariableRuntimeDxe assertions. Trace the dependencies of the display and logo DXE entries before changing their order. Done means the firmware reaches logo initialization without dependency or related startup errors and displays the logo as early as intended.
