If i understood you question then you want to change uvm info verbosity from UVM_LOW to UVM_NONE through command line argument.
//Option 1: This command line argument will change all the uvm_info verbosity to UVM_NONE irrespective of ID value.
//UVM_NONE is lowest verbosity level. `uvm_info with UVM_NONE verbosity won't be printed in log.
+UVM_VERBOSITY=UVM_NONE
//Option 2:
+uvm_set_verbosity=<comp>,<id>,<verbosity>,<phase>
//all the uvm_info statement in "report phase" and after that with ID=UVM/REPORT/SERVER won't be printed
+uvm_set_verbosity="*,UVM/REPORT/SERVER,UVM_NONE,report"
//all the uvm_info statement in "run phase" and after that with ID=UVM/REPORT/SERVER won't be printed
+uvm_set_verbosity="*,UVM/REPORT/SERVER,UVM_NONE,run"
//all the uvm_info statement in "run phase" with any ID won't be printed
+uvm_set_verbosity="*,_ALL_,UVM_NONE,run"
//Option 3:
+uvm_set_verbosity=<comp>,<id>,<verbosity>,time,<time>
//all the uvm_info statement executed at 0ns or after that with ID=UVM/REPORT/SERVER won't be printed
+uvm_set_verbosity="*,UVM/REPORT/SERVER,UVM_NONE,time,0"
