Is there a way to dynamically change the base_url in a symfony project based on reverse proxy header-CodePudding

I'm working on an app, with the front(vueJS) and back(symfony with API-platform) separated on the same domain.
We have an NGINX reverse proxy that redirects url base on these rule :

domain.com/ -> front container on port 7000
domain.com/api -> back container on port 8000
domain.com/preview-mrXXX/ -> front container on port 7XXX
domain.com/api/preview-mrXXX/ -> back container on port 8XXX

The problem is that the symfony assets aren't found because the request are on the root url and not the api or preview url.
e.g: request goes to https://example.com/bundles/apiplatform/web.png instead of https://example.com/api/bundles/apiplatform/web.png

I could pass a base_url in some header with nginx but I still need to configure symfony to requests on /api/ rather than /.
