You can create new rule which exclude this block.

example:

modelName = 'Frame_Test_Sc';
open_system(modelName);
set_param(modelName,'CovMetricSettings','dcme','RecordCoverage','on');
% Select blocks with block type 'RelationalOperator' to add a filter rule for. 
bl = slcoverage.BlockSelector(slcoverage.BlockSelectorType.BlockType,'RelationalOperator');
filt = slcoverage.Filter;
rule = slcoverage.FilterRule(bl,'Tested elsewhere',slcoverage.FilterMode.Exclude);
filt.addRule(rule);
filt.save('blfilter');
csim = cvsim(modelName);
csim.filter = 'blfilter';
cvhtml('cov',csim);

When you want to exclude specified block, you can do as:

id = Simulink.ID.getSID('Frame_Test_Sc/Test_env/Controller/controller_chart');
bl = slcoverage.BlockSelector(slcoverage.BlockSelectorType.BlockInstance,id);
