fips-mode-setup(8) is used to check and control the system FIPS mode.
-When enabling the system FIPS mode the command completes the installation

of FIPS modules if needed by calling 'fips-finish-install' and changes the

+(unless the policy has already been set to FIPS plus subpolicies on top,
+in which case the currently active subpolicies is retained).
Then the command modifies the boot loader configuration to add
'fips=1' and 'boot=<boot-device>' options to the kernel command line.
When disabling the system FIPS mode the system crypto policy is switched

+to DEFAULT and the kernel command line option 'fips=0' is set.
+On transactional systems, enabling the system in FIPS mode with the
+fips-mode-setup tool is not implemented. To enable the FIPS mode in these
+systems requires the following steps:
+
+ 1.- Install the FIPS pattern on a running system:
+ # transactional-update pkg install -t pattern microos-fips
+
+ 2.- Reboot your system.
+
+ 3.- Add the kernel command line parameter fips=1 to the boot loader
+ configuration. To do so, edit the file /etc/default/grub and add
+ fips=1 to the GRUB_CMDLINE_LINUX_DEFAULT variable.
+
+ 4.- After logging in to the system, run:
+ # transactional-update grub.cfg
+
+ 5.- Reboot your system.
