The short answer is "No." MATLAB has no idea what the contents of the function_handle mean in a symbolic sense. You're better off creating it using syms in first place. A longer answer would be either to use the Symbolic Math Toolbox, as suggested by @A Danesh, or an approximation, as suggested by @Andrey.

27.05.2018 · The diff function works in different ways depending on the input. It either takes the numeric difference (shortening the vector length by 1), or calculating the derivative of a function handle. The first syntax would be diff (f (3)), while the second would be diff (f (x)).

28.03.2020 · The function will return 3 rd derivative of function x * sin (x * t), differentiated w.r.t ‘t’ as below:-x^4 cos(t x) As we can notice, our function is differentiated w.r.t. ‘t’ and we have received the 3 rd derivative (as per our argument). So, as we learned, ‘diff’ command can be used in MATLAB to compute the derivative of a function.
