Hello Danish,
You can achieve the same using setProperty method on testcase object.
You can refer to the following example
tf = sltest.testmanager.TestFile('someSimulinkTestFile');
ts = tf.getTestSuites % get first test suite object of test file
tc = ts.getTestCases % get first case object of test suite
setProperty(tc, 'SaveState', true) % for 'States'
setProperty(tc, 'SaveOutput', true) % For 'Output'
setProperty(tc, 'SaveFinalState', true) % For 'Final states'
setProperty(tc, 'DSMLogging', true) % for 'Data stores
setProperty(tc, 'SignalLogging', true) % For 'Signal Logging'
You can refer to this following page for other properties that you can modify for test case,
