Or just listen to indigenous women and offering them support. Your premise that indigenous women doesn't speak up is false.

Sure, some white women would be the "white saviour". Other would just offer a place were those indigenous women can talk. Remember Malala? She wasn't happy with the taliban:

It was her who wanted to study and not be forced into marriage. Her speaking for herself.

And google can provide plenty of examples of indigenous women all around the world not happy with being second class and speaking up for themselves. It is not western feminism, it is just people being unhappy when they are treated as second class.

And interestingly enough, some indigenous women consider western patriarchy and colonization the reason they have to endure patriarchy now:

Here, another feminist women who is not white:

So, my advice, don't assume that in other cultures there is no feminism. They have their own versions and we learn from each other.

Cultures evolve, not just western, but indigenous too.

So a suggestion: go to google and search for indigenous feminist. Then read what those indigenous women have to say for themselves. Sure, they would critizy western feminism, but they would also speak against patriarchy, western and indigenous. A good read if you ask me.
