No and no.
dhcpcd only accepts configuration via dhcpcd.conf or the commandline.
It does not look at per distro configuration.

It could be possible to get the init script to add the deny interfaces,
or allow interfaces directive to the command line moving forwards.
Hopefully someone more proficient than me with the Debian style
networking can patch that.

Add this to /etc/dhcpcd.conf, right at the top
denyinterfaces eth0
