Both Sony RX10 II and Sony RX100 VII have 1″ sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the RX10 II and RX100 VII sensor size comparison.
Sensor Size and Resolution Comparison image of Sony RX10 II and Sony RX100 VII Cameras
Sony RX10 II and Sony RX100 VII have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Sony RX10 II
or the
Sony RX100 VII ,
including hyperfocal distance.
