Maybe you need to modify the core source and build a libchrome.so yourself.
After some search, seems user agent is defined here:
https://cs.chromium.org/chromium/src/content/shell/common/shell_content_client.cc?l=23-29

So :( How to build? I have to follow by this guide?

First:
https://chromium.googlesource.com/chromium/src/+/master/docs/android_build_instructions.md
Then:
