Overall ASRock BIOS seems like the in-house AMI Aptio V BIOS engineer is behind schedule.
The interface layout is just hiding/unhiding Aptio V parameters (no customization or renaming of Intel terminology), and they did not have the time to set the conditionals and just published their ROMs to the public. Just like Gigabyte BIOSes. But Gigabyte has been doing this for the last decade, while it seems ASRock started having this behavior likely ADL onwards.
(i.e. typing core ratio limits on X group of settings which takes precedence over Y group of settings), it will seem like there's 16 boxes, or possibly 24 boxes to fill for just 8 P-Cores, but filling group X, it doesn't autofill group Y, group Z based on how it takes priority.
Users that haven't had experience tweaking AMI Aptio V Intel BIOSes will have a really difficult learning curve ahead with the modern power management (DLVR and tiles) especially on ASRock and Gigabyte.
On MSI, it will autohide and autofill (not exposed to the user) the If(s) and nested conditions. So the very complex menus are a lot more simplified.
Renaming of Intel parameters are done to the right level on MSI, renamed just enough to make it more understandable to a human being. However on Asus BIOS, DIMM Flex and all that overdone marketing fluff is just out there to trick uninformed buyers that they run some proprietary asus only feature when in fact they are just renaming and regrouping parameters/intel tech in AMI Aptio V available to all board vendors (Giga, ASRock, MSI, Asus and chinese vendors)
