yes it's not the most thrilling video but it does explain the issue in easy to understand terms.

is it possible to use LATCH instead or PORTx.x in PBP?

pretty easy for chips with LAT regs

in your case
LATA.0 =1
LATA.1 =1

note LAT(X) cannot be used with compound commands THAT auto set TRIS regs like SERIN,I2CIN,TOGGLE etc
