Enable Experimental Features on DockerHub Automated Builds

Hey there,
I’ve put {"experimental" : true} into /etc/docker/daemon.json in a build hook for DockerHub automated builds and now docker version outputs that experimental features for the client are enabled, but for the server it’s still on false.
Is it possible to enable experimental features for the daemon on DockerHub for automated builds?

I am also curious about this. I would like to build docker images with the --platform command-line option, but that is only available starting in server API version 1.38, and as of April 6, 2020, the server API version on DockerHub is 1.37. Here is the output of docker version in an automated build on DockerHub,

Version: 17.06.2-ee-6
API version: 1.30
Go version: go1.8.3
Git commit: e75fdb8
Built: Mon Nov 27 22:45:33 2017
OS/Arch: linux/amd64
Version: 18.03.1-ee-3
API version: 1.37 (minimum version 1.12)
Go version: go1.10.2
Git commit: b9a5c95
Built: Thu Aug 30 18:42:30 2018
OS/Arch: linux/amd64
Experimental: false

It seems that automated builds on DockerHub run within a Docker container. The Docker server is probably being used for many automated builds at once. I was not able to restart the Docker daemon with systemctl restart docker, which is necessary after changing the daemon config.
