Hi @alex_mendoza,
You will have to configure the EQ settings on an iPad or PC Roon Remote. Afterwards you can select the presets using your iPhone.
There is an issue with some DSP options not being displayed on mobile that has been resolved in our next Roon release (see DSP Options Missing on iOS (Build 401) [Ticket In]), but configuration will still need to be made on a PC or iPad and only presets will be visible in the mobile version.
