Which OS Build should I flash if I have a Sprint variant GM1925?

Good day everyone,
A couple of months ago I got my hands on a OnePlus 7 Pro 5G Sprint variant and one thing I don't like is that updates from the carrier are too slow, so I want to flash another Oxygen OS Build that can receive update directly from One Plus, I already unlock the bootloader using this guide: [BOOTLOADER UNLOCK] Sprint OnePlus 7 Pro 5G, also I use this guide to flash TWRP: [Guide] [Android 9/10] [7/7Pro] Unlock, TWRP, Root, and Update, and I know that the Oxygen OS Builds are here: [OnePlus 7 Pro (5G)][ROM][OTA][Oxygen OS] Repo of Oxygen OS Builds.
So, my question is: which OS Build should I use to change the Sprint OS variant to an international version from One Plus? I read on that page that for the Sprint variant GM1925 the GM25CC packages are the ones intended to be used but they are no longer supported, can I use the GM21AA variant for this even though my One Plus is not a double sim one?
Thanks for the help
Updates for OnePlus 7 Pro 5G phones are really slow due to the 5G modem. At best, you can debrand your Sprint phone to make it using the EU 5G ROM by following the guide here.
And, sad but true, you can't use any of the GM21AA, GM21BA ROMs.

Thanks for the help, my only concern by debranding it would be that if the EU 5G variant would affect the 3g, 4g or 5g bands supported by my current carrier

Question how to downgrade oxygen os 12 to oxygen os 11 with tmobile version??

Hello, I updated my one plus 9 to oxygen os 12 to test it and it seemed very bad to me as dowgrade to oxygen os 11 I have the tmobile version, can I change to global rom to downgrade it?
Just did this.
Have to use the T-Mo MSM. Using Global detected it as T-Mo and it refused to work.
After that, you can convert it to Global using the modified MSM and then apply 11.2.10.10 as normal.
Hi can anyone please share the links for downloading TMobile msm tool and also for the os 11.2.10.10
