At the moment it's an all or nothing. A driver supporting fine-grained system SVM can enable it in order to get full SVM support. Lower levels could be emulated by userptrs and placing the bo at the same locations in the GPU's VM as well, but that would require reworking quite a bit on the drivers side. For now supporting mmu_notifiers on the kernel side is the only way of getting SVM support with Rusticl. The only driver having the gallium bits wired up atm is Nouveau, but I suspect it shouldn't be all to hard for iris and radeonsi as well.
