Can you send Bitcoin with no fee?

I'm curious, is it possible to send Bitcoin with no transaction fee? I understand that fees can vary depending on the network congestion and the miner's fee, but are there any methods or circumstances where sending Bitcoin can be done for free? I've heard about batching transactions or using lightning networks, but I'm not sure if those are viable options. Could you please elaborate on this and any other potential ways to avoid paying a fee when sending Bitcoin?
