Disable replies to ping on Pepwave Max BR-1 Mini

I have a number of Pepwave MAX BR1 Minis (Firmware 7.0.1). There does not seem to be a control to enable / disable “Reply to ICMP Ping” like there is on a per-WAN basis on Peplink Balance products. Is there a (carrier / SIM) reason for this, or is this a reasonable feature request?

This is not supported by cellular WAN at the moment. This request has been filed and we will look into this.
