Why not just leave the frequency reference switched on. OK with a TCXO,
not so good with a Rubidium standard. Power consumption must be trivial
compared with the normal domestic base load.

As I see it, the only way out is to go into REF CAL from the Config menu
and then press 2 to disable XREF until the frequency standard has
locked.
Like you, I have found that if XREF is enabled when the K3 is switched
on, the K3 drifts unacceptably for 15 minutes until the frequency
standard has settled down.

I was wondering if there is any kind of "sensibility" check done on the
input reference?
For example, I've been fooling around with a double oven controlled XO.
Starting from cold it is > 200Hz off. It takes ten minutes or so to be
within 10 Hz. It gets into the tenths of Hz accuracy region in another
10 minutes.
Clearly one would not want the K3EXREF to lock to this oscillator
during the first 10 minutes or so.
