Can't install Kaltura batch server on AWS Graviton machine (arm64 support)

[Ronileco]

Would love to know if this is supported and if we can utilize AWS graviton machines.

As I tried installing the batch server on a graviton machine I received:

[root@ip-10-0-0-238 ec2-user]# rpm -Uhv http://installrepo.kaltura.org/releases/kaltura-release.noarch.rpm

What am I missing here?
