How do you use a read only bind mount in Drone?

The docker docs state that a read-only bind mount may be accomplished in one of two ways:

Using --mount:

 docker run -d \
  -it \
  --name devtest \
  --mount type=bind,source="$(pwd)"/target,target=/app,readonly \
  nginx:latest

or using -v:

docker run -d \
  -it \
  --name devtest \
  -v "$(pwd)"/target:/app:ro \
  nginx:latest

A docker inspect turns up:

"Mounts": [
    {
        "Type": "bind",
        "Source": "/tmp/source/target",
        "Destination": "/app",
        "Mode": "ro",
        "RW": false,
        "Propagation": "rprivate"
    }
],

Is there a way to get this working in a Drone pipeline?
