This property should be generic. It is defined by IEEE 802.3cg 2019 and can
be implemented on all T1L PHYs.

I assume, it should be something like:
ethernet-phy-10base-t1l-2.4vpp-enable
ethernet-phy-10base-t1l-2.4vpp-disable

'ethernet-phy-' is a bit redundant and I'd make it a tristate (not
present, 0, 1). So just '10base-t1l-2.4vpp'?

To overwrite bootstrapped of fuzed values if supported. The IEEE 802.3cg
specification uses following wordings for this functionality:
"10BASE-T1L increased transmit level request ..."
