Why the specific ROM can't be found anywhere?

To who it may concern,

I own an Honor view 20 (C185E5R3P3) with Android version 11.0.0.161. Unfortunately, the has a malware and it needs to be flashed. This ROM can't be downloaded from anywhere. I would appreciate the significance of your help to provide the ROM file.

Faithfully yours,
