how to change the SPICE simulation engine from SIMetrix to LTspice in ee.spice.s​emiconduct​orSubcircu​it2lookup

I want to change the SPICETool to LTspice. I am trying to parameterize a sic mosfet using this function like in ee_SiC_mosfet_tabulated example. here is the code I'm using

%% Set Lookup Table Data From a SPICE subcircuit

%% Description:

%

% Generate lookup table data from a SPICE subcircuit file and set lookup

% table parameters for the N-Channel MOSFET (Lookup Tablez-Based) model.

% Copyright 2022 The MathWorks, Inc.

%% Open model

model = 'ee_SiC_mosfet_tabulated';

if ~bdIsLoaded(model)

open_system(model)

end

blockName = [model, '/N-Channel MOSFET'];

%% Set the SPICE simulation parameter to extract lookup table data

subcircuitFile = fullfile(matlabroot, "toolbox", "physmod", "elec", ...

"eedemos", "applications", "devicecharacteristics", ...

terminals = [1,2,3,0,5]; % Terminal orders in the subcircuit

% Define the gate-source voltage range, drain-source steps, and temperature

% steps for the transfer characteristics of the SiC MOSFET

%% Generate lookup table data from the SPICE subcircuit

% Uncomment the code below to generate lookup table data if you have

% installed SIMetrix

save('lookuptable.mat','lookuptable') % Save the lookuptable data in a MAT-file.

%% Set lookup table parameters for the N-Channel MOSFET

% Load the lookuptable MAT-file

% Setup channel parameters
