Hope this may help you.

If you like to change the excerpt value then the file is inside theme folder -> inc -> functions -> functions.php on line no 148, you can change the value 50 to your wish.

But before making changes in the code first make a child theme so that updating to new version. your customized code will not be lost.

Thank you!
