Yes, small ones for industrial use. They're extremely expensive, however.
Looking at the raw NAND flash prices, SLC seems to still be around $4.60USD/GB, or roughly the same as it was over a decade ago, while MLC is already <$1USD/GB despite only a doubling in capacity. TLC and QLC seems to be down in the $0.10USD/GB. You can still buy raw SLC NAND flash in the smaller capacities of few GBs; this one is only 512MB, at the price mentioned above:

If the pricing was sane, SLC drives would be only 4x more expensive as QLC ones for the same capacity, but that's not what we're seeing today.
