boot messages should remain hidden at bootup even after pressing any keystrokes

I have a CentOS system and I want to prevent the boot messages from appearing during bootup. I have added the quiet option in grub.conf file which hides the boot messages, but after pressing the esc key or the arrows it shows up again.

Is it possible to hide it permanently?

Or not show the boot logs when the basic(esc or arrow) keys are pressed but assign a different set of key combos which when pressed, then only the boot messages should be visible.

You're playing with hot stuff - usually people try to make the system as verbose as possible, especially during the bootup phase.
When you manage to set this up you'll then be completely scr*wd when you'll have some kind of problem (will happen 100 AND you won't have any network connectivity).

Having said this, you could play with the contents of "/etc/inittab" (or similar on CentOS) => you should be able to get rid of ALL the messages on the primary console and login manually from the secondary one.
WARNING-WARNING-WARNING: if you misconfigure "inittab" your boot will get stuck and you'll probably have to mount the storage directly on another PC (or boot some kind of live/recovery-CD) to be able to change its configuration.
