To disentangle the role of shell effects and dynamics, fission fragment massdistributions of $^{191}$Au, a nucleus in the newly identified island of massasymmetric fission in the sub-lead region, have been measured down toexcitation energy of $\approx$20 MeV above the fission barrier via twodifferent entrance channels, viz. $^{16}$O+$^{175}$Lu and $^{37}$Cl+$^{154}$Smreactions. Apart from having signature of the shell effects in both the cases,clear experimental evidence of quasifission has been observed in the massdistributions of the Cl induced reaction, that has also been substantiated bythe theoretical calculations. This crucial evidence along with a systematicanalysis of available experimental data has revealed that the dynamics in theentrance channel has significant influence on most of the reactions usedearlier to explore the persistence of recently discovered mass asymmetry in$\beta$-delayed fission at low energy in this mass region, ignoring which mightlead to ambiguity in interpreting the heavy-ion data.
