Yes. The DOP is 8 on the table and 12 on the indices.
What I noticed is that I can do
alter session FORCE parallel ddl
and that would result in my command running with DOP of 96. This however
will probably take all the resources of the server.
Thank you

Just checking, you do have "degree" defined as greater than 1 on those
indexes?
