Earn-out workarounds? (forgivable note, side letter, erosion clause, etc.?)

I'm looking at a deal with significant volatility in###-###-#### 2x previous years), and unsurprisingly the owner claims the change the structural and wants to be paid for it. I'm looking for a way to de-risk the deal based on an "earn-out" while using an SBA loan.
The easy answer here is that earn-outs are explicitly prohibited, but I keep hearing about potential work arounds where you can get the same function without it being considered as an earn-out by the lender.
Thanks in advance for the help.
