How to update "hidden" param in standalone reference configuration?

When code generating I get following warning:

Warning: Insufficient space for computing symbol names in model 'my_ref_model_name'. The

maximum identifier length '31' does not provide sufficient space to make symbol names unique using the

symbol format string in 'Global variables'. This is required when using model reference. Consider

increasing the maximum identifier length. To eliminate this message enter the command

set_param('my_ref_model_name', 'ModelReferenceSymbolNameMessage', 'none')

at the MATLAB prompt.

I am ok with the warning and I want to eliminate the message. But when I try to run:

set_param('my_ref_model_name', 'ModelReferenceSymbolNameMessage', 'none')

I get this error:

Parameter update is not supported for a configuration reference. Update parameter in the configuration

set that it references.

How can I update this parameter, if my reference configuration is saved in standalone data dictionary and my_ref_model_name is just referencing it?

(I can change configuration params that are visible in GUI for configuration editing, but I do not know how to modify the "hidden" params)

You need to open the data dictionary and change this parameter in the saved reference configuration directly.

I used workaround described here to get that reference configuration:

It woorks, but it is somehow not convenient. (For params not exposed in GUI.)
