Is there a way to reduce the size of the library being used in geckoview? like the libxul.so?

[m182s]

I was wndering if I can reduce the size of the library used by geckoview,
One of the biggest lib file is libxul.so, is there a way to reduce the size during building of the gecko binaries?
I tried some options in mozconfig like the following:

ac_add_options --target=i686-linux-android
ac_add_options --enable-optimize
ac_add_options --disable-debug
ac_add_options --disable-debug-symbols
ac_add_options --enable-release
ac_add_options --as-milestone=release
ac_add_options --enable-official-branding
ac_add_options --with-branding=mobile/android/branding/official

currently I got libxul.so size of ~50mb inside aar file.

any ideas in reducing components and features?
