Is it possible to poll devices with ICMP ping requests without using either the netxms agent or an snmp agent?
Yes, it's possible.
You can do it in a two ways:
1. Just add device you wish to poll as a node. If node doesn't have neither NetXMS agent nor SNMP agent, NetXMS server will use ICMP ping to determine is it responding or not and change status accordingly.
2. Load PING subagent on any managed node, and use any of ICMP.xxx parameters to send ICMP pings. In this case, you can monitor not only reachable/unreachable status, but also ping response times. You can find additional information about PING subagent here: https://www.netxms.org/documentation/ping_subagent.shtml (https://www.netxms.org/documentation/ping_subagent.shtml).

But then how can we measure the exact latency and/or packet losses if I use method 1?
You cannot measure latency or packet loss with method 1. If you need it, you should use method 2.
