Not really: if VFPv3 is enabled, so is VFPv2, see the conditions:
https://git.buildroot.org/buildroot/tree/arch/Config.in.arm#n21
and see the reasons below...

Unless I'm mistaken, that's already the case, and has been so at least
since 2013:
5f959a1c arch: improve ARM floating point support and add support for EABIhf
21 config BR2_ARM_CPU_HAS_VFPV3
22 bool
23 select BR2_ARM_CPU_HAS_VFPV2
[--SNIP--]
30 config BR2_ARM_CPU_HAS_VFPV4
31 bool
32 select BR2_ARM_CPU_HAS_VFPV3
