The procedure is the same as with any bittboy, I'm sorry right now that I can't put you through all the detailed steps, but any guide like the one you can find on the miyoo cfw website will be worth it.https://github.com/TriForceX/MiyooCFW
Simply instead of using the image that they provide you, use the one from the link that I have put for you.
Don't worry as there is no possibility of your console breaking, just use another sd card to do this type of test.
You can skip the step of resizing the game partition size if you are only going to test if it works, if it starts well or if the screen is correctly seen.
If everything was correct you should resize the partition of the roms to take advantage of your card if it is 16GB, 32GB or more.
You already tell us if you have been lucky.
