We have previously addressed a similar question here:
As a general rule, the ‘reject re-apply’ period lasts for ~1.5/2 years.
I am pretty sure that being referred by a partner would not help as he would go against the feedback that his colleagues (partner colleagues) have given about your interviews.
Having said that, I don’t know the detail about your personal case but if you do have a direct connection with a partner and you have a close relationship with him, I would suggest explaining him your situation and why you got rejected to see if he can help you somehow. I am sure he can give you great advice and you can always re-contact him once the freeze period has passed.
If you do not have a close relationship with him, I would highly recommend you to avoid asking him to be a reference during the reject re-apply period.
I hope this helps,
Best of luck,
