From , you can explicitly add specific option directives on .asc schematics, then to the auto-generated netlist:
You do not need to look in the LTwiki's "undocumented" options for that.? It is standard in LTspice, in fact in all SPICE programs.? LTspice's Help is somewhat terse about it and does not show you how to add the .options command, assuming that you know how to add SPICE Directives already.?

.options gmin
.options gshunt
.options gfarad
.options gfloat
The correct format should be something like this:
.options gmin = 1e-14
.options gshunt = 0
.options gfarad = 1e-13
.options gfloat = 0.001
or this:
.options gmin = 1e-12 gshunt=1e-13 gfarad=1e-14
where each option is given a numerical value.

BTW, just few days ago, I realized that LTspice can run a netlist directly (just open the netlist and run it).
I believe that this has been somewhat restricted now, in LTspice version 24.1.? Previous versions generated a SPICE Netlist file when they ran, which was saved on your drive but deleted when LTspice is closed.? Version 24.1 no longer generates a runnable SPICE Netlist file.? I believe it can still run (process) a Netlist file if you have one, but saving one might no longer be an option.? I could be wrong.
