Tibetan Buddhism, can you burn a paper mantra wheel in front of the grave of the elders?

The offering of fire is a ritual dedicated to protecting the Buddha in Tibetan Buddhism, and it is also a ritual in practice. That is to say, first of all, the object of offering is the Buddha, the protector of Buddhism, and it is generally unbearable without such an identity. In addition, the fire offering is a kind of sacrificial ceremony for practitioners who practice Tibetan secrets, which is different from burning paper for your predecessors, so I suggest not to do so and pay more paper money.
