ONEPLUS 9 LE2110 (china model) compatibility

Hello, I just bought a Chinese OnePlus 9 (LE2110) for the sole purpose of installing IodeOS, so I came to ask you if Iodé is compatible?
(Obviously the seller had not warned me that it was a Chinese version) OxygenOS 11 is installed on it in global version, but strangely impossible to upgrade to v13…

Model versions supported by iodéOS are: LE2110, LE2111, LE2113, LE2115

It is easily possible to change the firmware version with a corresponding OnePlus Fastboot ROM.
