If you want to disable them completely, just head to C:UsersUSERNAMEAppDataRoaming.technicmodpacksattack-of-the-bteammods and delete the file with the name "World of Dinos." Then, the closest thing to a dinosaur you should see is the occasional pack of iguanas. Be sure to replace USERNAME in the file path with the account name you're using on your PC.
Hope this helps!
