How to download the telegraf-operator image for OCP platform

We have OCP platform, and trying to install telegraf-operator to the container to collect the container infra metrics. But we have restrictions to download the operator from quay.io we traffic cannot be allowed.
Is there a way i can get the image downloaded, so we can keep in the artifactory inside the network and access the same.
I referred this, but i cannot use the helm commands, as its referring to influxdata site again to download the operator.

Can there a placeholder where image can be build and kept?

Have you considered using something like quayctl to download the squashed docker image that you want and then upload it to whatever your systems can access.
