=SUBSTITUTE(PROPER(SUBSTITUTE(A20,"_"," "))," ","")

It first replaces _ for a space character. Then creates Caps for the first character after the space and finally removes the spaces.

If you truly only need the character after _ to be in caps, then use this Office 365 solution:

=LET(cell, A2,
     a,    SEQUENCE(LEN(cell)),
SUBSTITUTE(
           REDUCE( A20, a,
           LAMBDA( b,   c,
IF(MID(b,c,1)="_",
   LEFT(b,c-1)&UPPER(MID(b,c,2))&RIGHT(b,MAX(a)-c-1),
   b))),"_",""))
