CentOS force dnf to use mirrors of a specific location

Using CentOS 8. I would like to force dnf to only use mirrors in the vicinity of a certain location without having to manually maintain a list of desirable mirrors. So I looked to modify the repo config files in /etc/yum.repo.d/. Take /etc/yum.repo.d/CentOS-Linux-BaseOS.repo for example, this is its default state:

[baseos]
name=CentOS Linux $releasever - BaseOS
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra 
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

I would like to know if there is a parameter when querying mirrorlist.centos.org I can specify to filter by location, something like this:

mirrorlist=http://mirrorlist.centos.org/?country=us&other-params-ommitted 

(country= I tried, didn't do anything) I haven't been able to find any relevant documentation on the site's API.
