Default can the compensation capacitor value be reduced in this circuit?

want to get more damping factor atleast 50V/us or using the compensation capacitor as low as 8pf

I do agree that in order to sustain a power bandwidth the slew rate is supposed to be increased but overall i just cant see 9V/us bandwidth in the amp... I would like to increase it..

From appnote:

Table 6. LME49830 Slew Rate vs Compensation Capacitor
Compensation Slew Rate
Capacitor, CCOMP (pF) (V/s)
5 110
10 55
12 46
15 37
18 31
20 27
25 22
30 19
60 9
100 5.5
