You can use the --type flag to uninstall a specific SDK type. Providing the flag when uninstalling works similarly to using the flag when installing an SDK or searching for available SDK types.
For example, use the following command to uninstall the nRF Connect SDK Bare Metal option:
nrfutil sdk-manager uninstall v2.8.0 --type nrf-bm
You can also use the --type flag with the sdk uninstall subcommand.
For example:
nrfutil sdk-manager sdk uninstall v2.8.0 --type nrf-bm
