How do you get rid of the VariableNamingRule warning when you do want it set to modify ?

Hi, I have the following code:

opts = detectImportOptions(fullfile(file_B_path, file_B_name)); % Detects import of table
opts = setvartype(opts, 'ID', 'string'); % Sets ID to string datatype
opts = setvartype(opts, 'RvCCompliance', 'string'); % Sets RvC Compliance to string datatype
---> opts.VariableNamingRule = 'modify'; 
file_B = readtable(fullfile(file_B_path, file_B_name),opts); % Imports table

and I keep getting the following warning:

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before 
creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

I know that variablenamingrule is set to modify, in fact, I want it to be set to modify. Why wont adding the line with the pointer get rid of this messege ?
