change of routine?

hello im just wondering about pheabeas daily routine as at the moment shes used to being fed pellets at night around 7 however the problem is i worry she is eating it all at once and then feels hungrey for the rest of the day she gets hay provided all the time so she has this and vegetables at 6-7 time too

can i change so i can maybe allow her to eat half her pellets in the morning then half at night or stick to the routine shes used to and maybe give vegetables in the morning

im just wondering as i know that an change in routine can use upset should i just change one day and stick to it or do this slowerly somehow???

I feed the veg in the morning and pellets in the evening so its split between the day. They also have hay toputs through out the day.
