Is it possible that in survival mode, after 30 minutes, these tanks can appear, instead of the usual normal tanks?
Just change that.

If not, can you add a configuration based on this plugin, to make it possible?

EDIT:
Can only spawn mutant tanks in 3rd round escape finales ?
If not, can add cvar to make it?

// Spawn Mutant Tanks during finales only. // 0: OFF, Mutant Tanks will spawn on any map. // 1: ON, Mutant Tanks will only spawn on finale maps. // 2: ON, Mutant Tanks will only spawn on non-finale maps. // 3: ON, Mutant Tanks will only spawn on finale maps before the rescue vehicle is called. // 4: ON, Mutant Tanks will only spawn on finale maps after the rescue vehicle is called. "Finales Only" "0"

EDIT2:

Can add enable only in 1st wave of finale 0-1 mutant tanks + the normal tanks defined in the vscript (example: vscript 6 tanks, then 0-1 mutant tank and 6-5 normal tanks), in 2nd wave of finale 1-2 mutants tanks + the normal tanks defined in the vscript (example: vscript 8 tanks, then 1-2 mutant tank and 7-6 normal tanks) and in 3rd wave finale escape infinite mutant tank? (the limit must be defined in the vscript).
