is it possible to block the bootloader to use the GPIOs as input pins which could be LOW during the boot process or is there any combination of GPIO0 and GPIO2 which doesn't triggers the bootloader even if one is LOW?

Thank you!

Edit: Changed the question to clarify what I want.

to run the application, tie GPIO0 to high

So I'm looking for a solution to block the bootloader or to use the GPIOs in a combination which doesn't triggers the bootloader but I can't find a solution.
