How do I save changes to an edf file that was generated from EyeLink?

How do I save an edf file that was generated from EyeLink (that I have made a minor modification to) as an edf file? I have an edf file generated from EyeLink. I made one change to one of the values in a field, and want to save the edf file with this one change intact and want everything else about the structure of the file to remain the same. However, I can't find a way to save the file as an edf file with everything in place. I can save it as a .mat file but have not been able to save it as an edf file. Thank you for your help
Trials= edfImport('C:\Users\Lab\Desktop\M\Experiment\Unprocessed Subject Data\025\025_ED.edf', [1 1 1], '');
if find(~any(~isnan(Trials(i).Samples.pa(2,:))))==1 %this tells you to find rows that have all NaNs
Trials(i).Samples.pa(2,:) = NaN; %fills the B column tally with NaN
save('025_ED_C','-struct','Trials')%this does not work. it saves it as a .mat file and I would like it to be saved as an edf file

The save command by default saves a given file as a MAT-file. MathWorks provides support to work with EDF/EDF+ Files through various functions. These are listed on the following documentation page under the "Functions" category "Datastores and Data Import": https://in.mathworks.com/help/signal/machine-learning-and-deep-learning-for-signals.html
The EDF file can be directly modified using the command edfwrite.
You can also refer to the linked file exchange which contains the function "SaveEDF" to save a file as an EDF File.
