The feature can be switched off by running the following commands in the <server installation directory>\tomcat\spotfire-bin directory on the command line:

config export-config --force
config set-config-prop -n security.referrer-policy.enabled -v false
config import-config -c "Disabled Referrer-Policy"

If switched off, the feature can be switched on again by running the following commands:

config export-config --force
config set-config-prop -n security.referrer-policy.enabled -v true
config import-config -c "Enabled Referrer-Policy"

You can change the referrer policy directive using the following commands (where the input to use is the desired directive):

config export-config --force
config set-config-prop -n security.referrer-policy.directive -v no-referrer
config import-config -c "Updated Referrer-Policy directive"

See documentation about available directives for the Referrer-Policy HTTP header on, for example, Mozilla.
