Hi! Did not find any guides about it. Interesting to make such a control frontend for AKM and ESS DIY boards. Something like small OLED screen + encoder and (stm32 ?) development board. But what about coding ?

When making GUIs, object oriented programming and pointers are your friends. For example
Code:
struct option // simple option structure
{
char *name; // option description
};
struct page // simple page structure
{
char *title; // Page title
unsigned short int page_no; // Page no
unsigned short int option_count; // Number of options
struct option page_options[4]; // 4 simple options max
};
struct page page1;
struct page page2;
and so on ....Then what you basically do is move the cursor between options or redirect between pages (using pointers) according to the buttons pressed. While every function / feature doesn't apply to every page some controls like volume, mute etc. should work on any page. It's tedious to get into the finer details of things but I think you'd get the general idea.
Hop that helps.

I'm noob in programming, remember only Basic from ZX Spectrum. Hope that may be it possible to correct the finished existing code according to DAC specific settings.
Maybe take a look at this stuff:

If you're looking to extract the code, modify and put it back in, then I think that doesn't quite fall into the beginner's league. Besides, you're linking to a China board ...
