I have a valid(?) PCAP file created by a router/Gateway, that contains
HDLC-LAPB and X.25 L3 PDUs. Using the Analyze => Enabled Protocols and
disabling all but the above mentioned Protocols I cannot persuade Wireshark to
decode the contents of the trace file.

I enclose the PCAP file containing the aforementioned trace.

Frame 1: HDLC LAPB SABM PDU
Frame 2: HDLC LAPB UA PDU
Frame 3: HDLC LAPB DT PDU / X.25 Call Setup PDU
etc.
