Combination of NAT modes and load-balancer algorithms

[evladse]

I noticed that in case of "dsr" for loxilb.io/lbmode we can use only "hash" in loxilb.io/epselect
Is there any description about combination of these parameters?
For instance in doc section we can read about NAT modes (for instance L2-DSR or L3-DSR) but in lbmode description section I can see "dsr". is it possible to use L2-DSR or L3-DSR?
According to doc section for "Load-balancer algorithms in loxilb" there are no any words about "n2" or "n3" or "fullproxy" for lbmode but
I can see some description about combination like below
loxilb.io/lbmode: "fullproxy"
loxilb.io/epselect: “n2”
“fullproxy” lbmode combined with “n2” epselect is being used for L7 load balancer rule.
