Is memory for CLR SSIS module included in the memory reserved for SQL Server 2017?

I have many issues like this in my SQL Server 2017:

Mensaje AppDomain 16 (SSISDB.dbo[runtime].26) is marked for unload due to memory >pressure.

Should I increase or reduce the "max memory" parameter?

More generally, is the memory for CLR SSIS module included in the memory reserved for SQL Server?

Thanks in advance,
