Use of surface mounted device (SMD) will certainly help with reducing the number of thru-hole on the PCB, however, it would not reduce the amount of blind or buried vias as the copper connection would still be necessary for the PCB to function. 

Also, very important to note that using SMT is significantly more expensive than using thru-hole for small scale projects, as SMT requires the use of reflow ovens whereas thru-hole components can be hand or wave soldered.
