I developed a tool that allows making changes to pcap layers. You can use it to remove any layer by simply providing its offsets.

e.g. To remove the Ethernet layer,

python3 modify_layers.py -i test.pcap -l "(0,14)"

As far as I know, scapy does not have a particular method for stripping layers but scapy's method remove_payload() can come handy in situations like this. What you can do is.

pkt=IPv6/IPv6ExtHdrRouting/ICMPv6EchoRequest
pkt2=pkt[ICMPv6EchoRequest]
pkt[IPv6].remove_payload()
pkt /=pkt2

Which will leave you with your desired output.
