Remove vs type field (eg. ip-forward or l2-forward) using TMSH?

I'm trying to get around tmsh config editing. I made following standard test vs:

destination 192.168.2.0:any
mask 255.255.255.0
profiles replace-all-with {
    ipother{}
}
source 0.0.0.0/0
translate-address disabled
translate-port disabled

Then I modified vs using tmsh by adding

l2-forward

field:

destination 192.168.2.0:any
l2-forward
mask 255.255.255.0
profiles replace-all-with {
    ipother{}
}
source 0.0.0.0/0
translate-address disabled
translate-port disabled

And now I'm unable to remove this field. When I use

edit

command, remove this line and save - nothing happens. I can't seem to use

delete

command on this field (

delete ltm virtual test l2-forwarding

) either because it says that

l2-forward

is read only property. So how can I remove this field from vs using tmsh? GUI allows to change vs type to standard and such operation removes this line from config but I don't know how to achieve this using tmsh
