True. There are different ways to ground morality, and while some philosophers argue for grounding it upon foundational moral values, others argue for grounding it upon foundational non-moral values. For example, some may ground morality upon values such as rationality, well-being, or human dignity, rather than upon specific moral principles or duties. This approach is sometimes called a non-moral foundation of ethics.
One argument in favor of grounding morality upon non-moral values is that it allows for a more objective and universal foundation for ethics, as non-moral values may be seen as more fundamental and less culturally contingent than specific moral values or duties. However, others may argue that non-moral foundations may still be influenced by cultural and subjective factors, and that grounding morality upon specific moral values may provide a clearer and more precise guide for moral action.
