RD value configuration error

Once the RD value configured under a VRF cannot be removed ???? am i
correct

i mean if u configured the RD value wrong
than can u remove it by simply adding no in front of command

or u have to remove the whole VRF configured

and once we remove the VRF, the every configuration is removed related to
 VRF
so in exam it could be worse if we cam to know after the Configuration whole
task or section

so , can we remove the wrong value by adding it no rd ___
or we have to remove the whole VRF
