For config options that are an array of arguments/parameters, issue commands like this:
lnms config:set bad_if_regexp.+ "/^tunnel_(.*)/i"
and remove options like this (where the number is the item in the list (zero inclusive))
lnms config:set bad_if_regexp.3
For arrays that are setup for key=>value, reference the array element using the key.
