Put the vive lighthouses in opposite corners of your room against the wall pointing downish. They should be alright seeing past the tables and desk because you probably don't get too close to them while facing them and I'm assuming they're not super tall.
Stick on hooks (called command hooks in my country) rated to about 1kg, a standard camera mount screw and a piece of metal with holes in it for the hook and screw. No drilling required. Could make it a touch more stable with a bit of blutac.
