Workaround
How to configure it in FMC Flex Config:
You can try the following command in the FlexConfig Object.
?crypt map CSM_outside_map 1 set nat-t-disable?
Please be advised of the following caveats:
1. FlexConfig object has to be created with Deployment as ‘EveryTime’ and Type as ‘Append’. If you configure Deployment as ‘Once’ in FlexConfig Object, then the command will be removed in the next deployment.
2. If you make Deployment as ‘EveryTime’, the command will be removed and added back in each deployment.
3. Please be cautious in using this command FlexConfig. If FMC changes the seq_number, then the deployment will fail
