Yes, sure.  S/R is a conflict bw a rule (reduce) and a token (shift).
Since you want the shift here, the token must have precedence over the
rule (or both have the same precedence but right associativity).

The rule is labeled by T_IDENTIFIER, so you can just state that

    %nonassoc T_IDENTIFIER
    %nonassoc '('

to get what you want, use use %prec to label the rule with some other
precedence/associativity token.
