Absolutely!
Right now i don't have a HACMP-system at hand to check the details myself, but: yes, that is (still) possible and in fact is the recommended way to do it.
Mounts will be done by a sort-of start/stop-Script HACMP provides for itself, its name is "clas-nfsv4" or something similar (again, i can't check and am working from memory) which will be entered automatically when you configure an NFS-mount and/or -export. I am not sure if one can configure the order in which this and your own application-server is called but if you want to be perfectly sure configure the NFS-services in its own RG, then configure a start before/stop after-dependency with your application RG.
I hope this helps.

nfsconfig
nfsconfig(8) System Manager's Manual nfsconfig(8)
NAME
nfsconfig - Launches the SysMan Menu at the Network File System Configuration (NFS) level, where you can configure a system as an NFS
server or as an NFS client
SYNOPSIS
/usr/sbin/nfsconfig
/usr/sbin/sysman nfs
DESCRIPTION
The NFS Configuration section of SysMan Menu is used by the System Administrator or the UNIX system manager to manage NFS configuration
issues.
It allows the system to be configured as an NFS server (to make its file systems available to remote machines), or as an NFS client (to
mount remote file systems).
Before using nfsconfig, be sure to configure Network Interfaces using the Network Configuration section of the SysMan menu.
You can configure your system as an NFS Server, an NFS Client, or both. However, if the Network Interfaces are down, the following daemons
will not start: nfsd, pcnfsd, proplistd, mountd, and automountd.
Use nfsconfig to do the following: Manage the configuration of the system as an NFS server. You can only configure your system as an NFS
server if the NFS Server option is built into the kernel. Manage the configuration of the system as client-only system Specify file sys-
tems to be mounted or exported Start and stop the NFS daemons
Online Help:
Online help is available for the NFS dialog boxes. You can get help by selecting the Help button on any dialog box.
