Yes,
there is.
transfer the files to a new server, if you have one, using the same file structures.
next create a init.ora file with the dbname and control_file parameters.
Start the instance using that init.ora in nomount.
If you happen to have snapshot controlfiles in $ORACLE_HOME/dbs/ of you database,
start rman:
rman target=/
restore controlfile from '/where/is/it/o1_mf_ncsnf_TAG20130803T022352_8zrqqfc4_.bkp';
alter database mount;
restore database;
recover database;
alter database open;
Without controlfile it's a little trickier but still possible. A nice explanation is here How to restore an rman backup without any existing control files
Tip: always end your backup by creating a copy of your current controlfile:
BACKUP AS COPY CURRENT CONTROLFILE FORMAT '/tmp/controlfile_%Y%M%D.ctl';
Preferably on a smarter location than /tmp. Not only does it contain your database layout, also the administration of your most recent and most valuable backup.
First you need to ensure that that the backup is in your library (surely you know better ways for find it, I put my query):
select
D.DB_NAME, B.DB_ID, BASET.BCK_TYPE,
decode(BASET.CONTROLFILE_INCLUDED,'BACKUP','YES','NO') as CONTROLFILE_INCLUDED,
BASET.INCR_LEVEL, bapiece.tag, bapiece.handle, bapiece.start_time,
bapiece.completion_time,
round(bapiece.bytes/1024/1024,2) as Mb
from rman.bp bapiece,
rman.dbinc d,
rman.bs baset,
rman.db b
where BAPIECE.DB_KEY=D.DB_KEY
and D.DB_NAME='SFPROD'
and BASET.DB_KEY=D.DB_KEY
and BASET.BS_KEY = BAPIECE.BS_KEY
and bapiece.start_time>sysdate-1
and B.DB_KEY=D.DB_KEY
--- and bapiece.handle like '%.dbf%'
order by tag desc, handle desc ;
And... I hate to use "set until time" to restore/duplicate database. It is more human friendly but you can be surprised with an rman error at the end of the restore. Try to find the last commit (SCN) for duplicate process:
SQL> select max(next_change#)
from v$archived_log
where archived = 'YES'
group by thread#;
or with rman:
RMAN> list backup of archivelog all;
--Next SCN
And then:
run { set until scn ... ; allocate auxiliary channel t1 type 'sbt_tape'; duplicate target database to DEVDB; }

One of the advantages of the FRA is that it is self-managing. IF you use the FRA, then when there is space pressure on it, any files that can be deleted will be deleted - automatically. With the FRA, you don't need your powershell scripts to try to manage your backup storage. In fact, you don't want your powershell script to manage your storage. Let Uncle Oracle and rman do it for you. You say the directories and file names it will create create are not the same as your PS scripts? Why does that matter, since Oracle is managing it all for you.
One caveat that a lot of people miss. Let's say you declare your FRA to be at '/u01/oracle/FRA'. Now, say you specifically specify a backup destination format of '/u01/oracle/FRA/mydb/20201008/'. Doing so is not using FRA functionality, and those files will not be known to be in the FRA, even though they are there and consuming space thought to belong to the FRA.
