Assuming you mean a PCI device, no, there isn't.

Without an IOMMU[1] you can't directly assign a PCI device to a guest
(nor is it safe).  There have been patches floating around to allow
this, but they don't maintain secure isolation.

[1] VT-d is an Intel chipset feature, so you could certainly do it on an
AMD platform that has an AMD IOMMU.
