When looking at https://ftp.osmocom.org/docs/osmo-hnbgw/master/osmohnbgw-vty-reference.pdf

Why are you looking at the OsmoHNBGW's VTY reference?
This command is only available in OsmoSTP, so: https://ftp.osmocom.org/docs/osmo-stp/master/osmostp-vty-reference.pdf

1.11.1 accept-asp-connections (pre-configured|dynamic-permitted) . . . . . . . . . . . . . . . . . . . . . . . . 101

I also see it in the XML output of osmo-stp:

$ osmo-stp --vty-ref-xml | grep "accept-asp-connections" 
Generating the VTY reference in mode 'default' (all commands except deprecated and hidden)
    <command id='accept-asp-connections (pre-configured|dynamic-permitted)'>
        <param name='accept-asp-connections' doc='Define what kind of ASP connections to accept' />
