OpenVPN scramble option

I've got OpenVPN up and running on my 18.06.5 OpenWRT. I have some Nord VPN OpenVPN config files that use the "scramble" option. This results in an error when I start this VPN connection:

Options error: Unrecognized option or missing or extra parameter(s) in /etc/openvpn/ scramble (2.4.5)

I presume that's because the OpenVPN package doesn't have support for this option compiled in. Does anyone know of a way to get this working? I've seen posts asking for it to be compiled in but haven't found any resolution.

have you asked the package maintainer to consider adding the patch set? Otherwise use the buildroot to add the patches during compilation.
