Sure. Just add the "ebgp-multihop" keyword to your neighbor statement in the "address-family ipv4 vrf" BGP section.

router bgp 64512
 address-family ipv4 vrf CUSTOMER
  neighbor 192.168.1.2 remote-as 64513
  neighbor 192.168.1.2 ebgp-multihop
  neighbor 192.168.1.2 activate 
  exit-address-family
 !
 exit
!

You can set the maximum hops too (minimum TTL on receipt).

On the CE side you just do this in global BGP (unless you use VRF's between PE and CE, in which case you do it the same way as above on the CE).
