If a substance can form hydrogen bonds, does that mean at the same time it doesn't form vander waals of dipole dipole forces as well even though it could?

Yes I think so, for example HF can only form H bonds because of the electronegative F bonded to a hydrogen. Even if there are vdw's, h-bonding would dominate and would be the strongest IMF present in the molecule. In questions particularly with ones containing vdw or dipole dipole they usually accept both.

Any molecule which expresses hydrogen bonding automatically expresses all 3 intermolecular forces.

Van der Waals are present between all molecules, it's not possible to not have VDWs.

Van der waals (aka intermolecular dipole induced dipole (IDID) bonds) are found in all bonds, hydrogen bonds are the strongest but IDID bonds are forever present

If a molecule is capable of forming hydrogen bonds as well as dipole bonds, will it form dipole bonds as well?
