It is not possible to skip, Only option is to change boot sequence.

Do you have an ethernet PHY connected to the ethernet boot port? If so, you may be able to keep the PHY in reset to prevent link. This may cut down on the timeout for the ROM. But ultimately, you should change the boot order.

keeping the PHY in reset should prevent link, which should shorten the timeout. Did you try this?
