While the Mi 9 SE may be one of the last in the Mi 9 series to receive Android 10 builds of MIUI 11, the wait for the OS upgrade is over. The update is available to download now, although it will only appear as an OTA for select handsets pending a wider rollout.

I don't know how you got into my google app news but I'm glad you did. Been waiting for an update about Android 10 for my Mi 9 SE phone for months because it took too long I thought Xiaomi forgot about us. Good to hear, kudos for the update
Hopefully it solves the horribly high standby consumption. It's fixed on "alternative" firmwares, but not having it fixed in the official builds kills me!
