Of course Miui roms from Xiaomi are compatible with all its devices but this doesn´t happen with custom recoveries, roms, kernels, etc.
Discover your kind of panel using a hardware info app like Aida or Device Info HW and put to the consideration of the developer of the rom.

The EDL cable is to force device to enter to EDL/download mode and you have to start it from device totally off, some devices like Xiaomi once they were unlocked (not before) enable this option by using a combination keys that is pressing the two volume buttons at exactly same time to connect device to pc through an USB cable.

It´s not possible as far as I know to flash an Android version lower than the Android version that came with device out of the box.
Not even you´re wanting an unsafe/risky downgrade but a chimera and I´m not referring to mithology.
Here you have a list rom collection and how to flash a stock rom onto your device https://www.getdroidtips.com/oneplus-5-stock-firmware/ but only a member that own this device can sure you that downgrading it you won´t brick it.
As a side note Xposed has some development working as a module inside Magisk environment and I think that the old Xposed development as in the old days is deprecated/outdated.
