To access the BIOS you would need to hit F2 at bootup. From there you would need to go to SATA SETTINGs, for sata ports or Boot mgr to change boot order.
Let me know if this helps.

Toogle Boot mode from UEFI to BIOS and lets if this helps to bring back some of the older options. Do you have alredy installed a modern OS onto the SSD? Because modern OS like Windows doesnt allowed to switch the mode after installation.

Hi,
R720XD does not support SATA optical drive, page 32: https://dell.to/36GUs9x
I don't think the setup is possible as the SATA controller is being replaced by PERC controller. You may not be able to detect the SATA connection.
