I was looking again at the Huawei servers. (new scan)
First security patch for EMUI 10 was released yesterday for the P20 pro. (July 20)
Well this apply _probably_ for the .161 build.
This update improves system security with Android security patches.
Integrates Android security patches released in July 2020 for improved system security.

There is also one regarding the CLT-L04 C792 (Canada) fixing certain networks instability. (this one is an update related to the cust package)
I may have to take a look at the code from Hisuite Proxy before because theses packages are named like: update_base.zip/update_cust_CLT-L04_default_ca.zip/update_full_cust_CLT-L04_default_ca.zip
Edit: From what I see from the code it will _probably_ work just like doing an upgrade/downgrade or whatever. There is also the FullOTA-MF.
I will update on the subject later.
Right now don't use them until I can confirm this.
Also theses files are not approved for installation at this moment.
Best regards
