I agree... these requirements are way too vague and not actionable at all:

Details matter.

The answer to most questions which start with "is there any method .... ?" is yes; but the "method" might require a lot of steps, changes, software, and more. Of course there are "ways" to do things.

Is there any method to "fly to the moon?" Is there any method to "cure cancer?" Is there any method to "restrict root?" Is there any method to "launch a car in orbit around the earth?"

Yes, yes, yet and yes....... but we must do a lot to get there and there are countless details.

The same is true for computer systems.

The answer is probably yes; but from the above, it is not possible to answer without myriad details.

systemd-volatile-root.service

SYSTEMD-VOLATILE-ROOT.SERVICE(8)			   systemd-volatile-root.service			  SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME

       systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile

SYNOPSIS

       systemd-volatile-root.service

       /lib/systemd/systemd-volatile-root

DESCRIPTION

       systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
       original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
       /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
       enabling fully stateless systems.

       This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
       line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
       service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
