How to execute timer functions in MATLAB GUI in parallel?

I have designed a GUI using MATLAB GUIDE. I need to execute two timer functions in parallel. Let's say we have a timer and its function defined inside the GUI as follows:
handles.data_acq_tmr = timer(...
'ExecutionMode', 'fixedRate', ...
'Period', 0.2, ...
'Busymode','queue',...
'TimerFcn', {@data_read, hObject});
function data_read(~,~,hObject,~)
handles = guidata(hObject);
% do some processing here
guidata(hObject,handles);
and the second timer as follows:
handles.dataproc_tmr = timer(...
'ExecutionMode', 'singleShot', ...
'StartDelay', 0,...
'Busymode','queue',...
'TimerFcn', {@data_proc, hObject});
function data_proc(~,~,hObject,~)
handles = guidata(hObject);
% do some other processing here
guidata(hObject,handles);
Is there any way to do it in MATLAB for instance using Parallel Computing Toolbox?

RZM - what are the callbacks for your timers doing? Are they performing complex and/or expensive operations?

Use parfeval in the parallel computing toolbox to asynchronously run the computationally expensive algorithmic (not gui updates etc.) part in the background. Use a timer to poll the job for when its state is "finished" for when it's done to update the user interface.

@Claudia-Elena Ilie's answer moved here.
By any chance, you understood how to rezolve your problem? I have something similar :)
