Until you get the fixed nozzles, you could try mounting an undamaged nozzle and adjust the incorrect/crazy high volumetric flow that Sovol has in its default profile. 17mm^3/s is crazy high, try 10 tops.
That should lessen the pressure buildup inside the nozzle. But it is still a bad nozzle design. There is a reason that lot of nozzle adapters have sprung up: Mount Bambu Lab clone hotends, MicroSwiss releasing their FlowTech hotswappable nozzles for SV08 etc.
