10baseT1S and 10baseT1L are both very niche technologies, so it's the sort of thing that is left to third parties.
There are existing evaluation boards for both.
Microchip EVB-LAN8670-USB evaluation board is a USB 10BASE-T1S interface. There are drivers for it in the mainline kernel at https://github.com/torvalds/linux/blob/ ... chip_t1s.c. Admittedly it isn't built in the standard Raspberry Pi OS kernel, but if reported as working then it's the sort of thing that could be added to the defconfig.
TI appear to be the 10baseT1L proponents, but I only see a RGMII interface to the PHY rather than a full USB network adapter.
The HAT form factor isn't as useful for 10Mbit networking as SPI is going to be at the maximum to support the full bandwidth, so you end up needing a USB link as well. There's very limited point in looking at the HAT+ PCIe interface for 10Mbit networking - it's total overkill.
