How to increase client_max_body_size in GCE ingress

[Luke0612]

Hi, guys

I'm using GCE ingress for our application based on PHP language. we have a feature to upload a large size to the server, we are getting now an issue related to the body request size, our request was exceeded more, and our files are always more than 2MB.  (The 413 Request Entity Too Large error is returned to the client every times upload)  https://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size

I am trying to increase the max post size with the ingress annotations as the Nginx ingress. When I attempt to add the following, it has no effect. I know, because it's different then the annotation is not affected on GCE ingress https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#custom-max-bo...
My question is How to increase this value on GCE ingress? Some person recommends an idea is to install a new Nginx ingress controller, but it isn't a good idea for me.

Any comments, any ideas all are very useful to me

Thanks for your time to read.

Best regards,
