Question about OEM unlock in Oreo

[zubair8xm]

Hi guys

I installed the Nougat Update and then i enabled the OEM unlock and then updated the phone to Oreo

Now here is the problem

Developer options were enabled and accidently i disabled them.
I know there is no option of OEM in oreo update.

Now my question is
Will OEM unlock be enable if i enable the developer options or i have to do it all over again.
Should i need to install nougat then enable OEM and then oreo update.
Or this OEM will be Enabled?

Please help.
