Is ICU supported on SRX240

Hello,

I have found in the docs that ISSU is not supported on Branch devices and that an option is to use ICU.

Is ICU suported on the SRX240 ?

I have found the following link which says ICU with no-sync in only supported on: SRX300, SRX320, SRX340, SRX345, and SRX550M

https://www.juniper.net/documentation/en_US/junos/topics/task/operational/chassis-cluster-upgrading-and-aborting-backup-and-primary-device-with-icu.html

Does this mean that is not supported at all on SRX240 or it is supported but without the "no-sync" ?

Thank you in advance for your answers
