OpenVPN custom options

[marco35]

Hi guys, been using OPNsense for a couple of years without issue. Presently using the latest, 27.1
I have come across a problem whilst trying to set up as an OpenVPN client to the VPN provider Cryptostorm.
I have the required settings delivered in an .ovpn file. Obviously, I have to interpret and fill in to the new 'instance' of OpenVPN.

My issue is, that the 'Advanced Configuration | Advanced' seems to have disapeared from the config page. As I understand it, this was always planned as it was considered insecure. However, as I understand it, I need to enter some custom config, and can't see where to do so.
Obviously I have entered the CA and static keys in the relevant pages - that seems fine.


Can anyone offer any pointers?
No secrets in the ovpn file so attached below for reference.

Thanks
