Is there any other way to treat worsening hallux valgus in a person in their 60s other than surgery?

I have a lot of concerns about my mom's feet these days, so I'm asking you a question.

My mother is in her 60s, and she has had hallux valgus for a few years now.
When I was young, I didn't have hallux valgus at all, and my feet were normal, but at some point, the shape of my feet started to change little by little. At first, I didn't feel much discomfort, so I just let it go, but as I get older, the shape of my feet seems to change more and more, and the symptoms seem to get worse.
In particular, if you walk for a long time, your feet will hurt a lot, and because your feet hurt, your calves and legs will also hurt.
I've had knee surgery before, so the foot pain is a bigger burden.
In addition, as the shape of the foot changed, the ball of the foot widened and the foot size also increased slightly.
So, there are many cases where the shoes you used to wear no longer fit and you have to buy new shoes... It is a situation where you feel uncomfortable in your daily life.

I've been to the hospital before, but not for treatment of hallux valgus.
I asked about this when I went to the orthopedic surgeon for another treatment.
The hospital said that it is indeed hallux valgus, but that it is not serious enough to require surgery right away. However, if the foot deformity gets worse and the pain continues to worsen, then surgery is the only option.
Even now, my second toe and little toenail are bent...
My mother said that it is natural for her legs to hurt when she walks for a long time because she is old, and that since her condition is not that serious, she is still very worried about the surgery.
Since he is not young, he is worried about the recovery process and wants to leave surgery as a last resort if possible.
But the problem is that, although it would be nice if the deformation stopped here, the shape of the foot continues to change slowly...

So, what I'm wondering is, in the case of hallux valgus, is there a way to alleviate the symptoms or slow down the progression of the condition other than surgery?

I bought braces a while ago, but I was disappointed that I couldn't use them outside.

Or, since I am currently in pain and deformity, will I eventually have to have surgery?
I also wonder if things like orthotics, shoes, and braces actually help.
